I picked slide one which is 2/3 + 3/4 and 5/6 + 2/3. To get 2/3 60. you have to divide 60 by 3 which is 20. that means 1/3 of 60 mins. is 20 mins, but you need to get 2/3 so you have to get 2 groups of 20 which is 40 mins. To get 3/4 you just have to divide 60 mins by 4 which is 15 mins. Then you need 3 groups of 15 which is 45 mins. then 45 mins + 40 mins. equal 1 hour and 20 mins. which also means 1 25/60.

to get 5/6 of 60 mins you have to divde 60 by 6 which is 10 mins. then you get 5 groups of 10 which is 50. if you look at it you dont have to do calculatons on 2/3 because we already did that. 2/3 is 40 minutes. if you add 50 mins. and 40 mins together you get 1 30/60


Thanks

I chose the one that has 3/10+1/3 and3/5+1/6. to get the answer of 1/3 you have to divide 60 to 3 which is 20. i need to get 3/10 so you have to divide 60 to 10 which is 6 so 1/10 of 60 minutes is 6. I have to add three group of 6 because the numerator is 3which is 18.

to get the answer 3/5+1/6 you have to divide 60 to 5 which is 12.I have to add three groups of 12 because the numerator is three which is 36. to get the 1/6 you have to divide 60 by 6 which is 10 so 1/6 of 60 is 10.

I decided to do 2/3 + 3/4 and 5/6 + 2/3 to get the answer i used the 60 minutes method you have to divide the denominator to 60 like 60 divided by 3 equals to 20 then you times it to the numerator number which is 2 so it would be like 20 times 2 would be 40 that's for the 2/3 question next one is 3/4 again you divided the denominator to 60 it would be like 60 divided by 4 is 15 then you times it to 3 which would be now 45 you add all of the answers that you got from 2/3 + 3/4 (40+45=85 minutes which is 1 hour and 20 minutes

the next one that we have to do is 5/6 + 2/3 = ? 60 divided by 6(denominator of 5/6) = 10 times 5 is 50 then 60 divided by 3 is 20 times 2 is 40 if you add 50(5/6 + 40(2/3) = 90 which is 1 hour and 30 minutes. 5/6 + 2/3 is bigger

i chose slide 1...

which is bigger?
2/3 + 3/4 or 5/6 + 2/3

2/3 + 3/4
2/3 of 60 minutes is 40 minutes because 1/3 of 60 minutes is 20 minutes...3/4 of 60 minutes is 45 minutes because 1/4 of 60 minutes is 15 minutes...so, 40+45 minutes is 85 minutes or 1 25/60...

5/6 + 2/3
5/6 of 60 minutes is 50 minutes because 1/6 of 60 minutes is 10 minutes...2/3 of 60 minutes is 40 minutes because 1/3 of 60 minutes is 20 minutes...so, 50+40 minutes is 90 minutes or 1 30/60...

2/3 + 3/4 is bigger!

i chose to do slide one , 2/3 + 3/4 and 5/6 + 2/3 . To find out which is larger first you do 60 divided by 3, then multiply by 2 . (60/3=20 x2=40) Then you divide 60 by 4 then multiply by 3. (60/4=15 x3=45) Then you have to add them together . (40+45=85) 2/3 + 3/4 = 85/60 or 1 and 1/4 .

For the next one you do the same thing . So it would be 60/6=10 x5=50. Then 60/3=20x2=40 . And then you add them together and it equals 90. 5/6 + 2/3 = 90/60 or 1 and 1/2.

2/3 + 3/4 < 5/6 + 2/3

i chose the first slide which is 2/3 + 3/4 and 5/6 + 2/3. i chose this slide because i thought this was an easy equation to figure. for 2/3 you have to divide 60 by 3 which is 20 and you multiply 20 by 2 which is 40. for 3/4 you have to divide 60 by 4 which is 15 and you multiply 15 by 3 which is 45. add 45 and 40 together which equals 85. or 1 25/60.

for 5/6 you divide 60 by 6 which is 10 and multiply 10 by 5 which is 50. for 2/3 you divide 60 by 3 which is 20 and multiply 20 by 2 which equals to 40. add 50 and 40 together and you get 90. or 1 30/60.

5/6 + 2/3 is bigger.

i picked slide number one. 2/3 + 3/4 would = 1 5/12. first you do 2/3, which means that you divide the clock into 3 equal sections. 60 divided by 3 = 20. 2 20's = 40. so 2/3=40. then you have to do 3/4 which means you divide the clock into 4 equal sections. 60 divided by 4= 15. 3 15's=45. so 3/4 = 45. 45+ 40 = 1 hour and 25 minutes. (we're adding both sums together so we can determine which one is bigger.) then you do the second part of the question. 5/6 + 2/3 = 1 1/2. first you do 5/6 which means you divide the clock into 6 equal sections. each section would be 10 minutes each. 5 10's = 50 minutes, so 5/6 = 50 minutes. then you do 2/3 which is 40 minutes. i've already explained it on the previous part of the question. so 40+50=1 hour and 30 minutes. therefore 1 hour and 30 minutes is greater than 1 hour and 25 minutes!

i chose 2/3 + 3/4 and 5/6 + 2/3. 2/3 is 40 and 3/4 is 45 mins, to get 2/3 you have to divide 60 by 3 then you will get 2 then you multiply it by 2 then you will get 40. for 3/4 you have to divid 60 to 4 then you will get 15 then you have to multiply 15 by 3 then you will have 45. you have to add the two numbers together and you will get the answer of 85 or 1 25/60.

5/6 is 50 mins because 1/6 is 10mins, times that by 5 it will be 5/6. 2/3 of 60 is 40 because 1/3 of 60 mins is 20 mins then multiply it by 2 is 40 mins. then you have to add 50 and 40 together and you will get the answer of 90 mins or 1 and 30/60.

5/6 + 2/3 is bigger.

i chose slide #1 because i thought that this is the easiest thing to solve. for 2/3 you just have you just have to divide 60 by 3 and the answer will be 20. you multiply 20 by 2 which is 40. for 3/4 you just have to divide 60 by 4 and the answer is 15 and you have to multiply 15 by 3 and the answer is 45. then, add 40 and 45 the answer is 85 or it will be 1 25/60.

for 5/6 you divide 60 by 6 and the will be 10 and multiply 10 by 5 and the answer will be 50. for 2/3 you divide 60 by 3 and the answer is 20 and multiply 20 by 2 which equals to 40. add 50 and 40 the answer is 90 or it will be 1 30/60.

5/6 + 2/3 is bigger.

I chose the 1st slide which is 2/3 + 3/4 because it think its the easiest. To get 2/3 i divided 60 by 3 and got 20, then you multiply by 2 because 2 is the numerator then you get 40 so 2/3 = 40. To 3/4 you just do the same thing so 60 divided by 4 = 15 multiply by 3 so you get 45. So you add 45 and 40 to get 85 minutes or 1 hour and 25 minutes, so 2/3 + 3/4 = 85/60 or 1 25/60.

To get 5/6 of an hour you just have to divide 60 by 6 to get 10 then you multiply by 5 to get 50, so then 5/6 of an hour is 50 minutes. For 2/3 you dont really have to do anything because we already did that in the other question so 2/3 is 40 minutes of an hour. so now you add 40 and 50 together and get 90 minutes or 1 hour and 30 minutes. So you get 90/60 or 1 30/60.

5/6 + 2/3 is larger.

I chose slide one because I thought it would be the easiest to solve. To get 2/3 you need to divide 60 by 3, the answer is 20. You then multiply 20 by 2, the answer is 40. For 3/4 you need to divide 60 by 4, the answer is 15. Multiply 15 by 3, the answer is 45. Then you add 40 and 45 together, that equals 85 minutes.
2/3 + 3/4= 85/60 or 1 25/60.

To get 5/6 of an hour you divide 60 by 6, the answer is 10 minutes. Multiply 10 by 5, the answer is 50. To get 2/3 you need to divide 60 by 3, the answer is 20. You then multiply 20 by 2, the answer is 40. Then you add 50 and 40, that equals 90. 5/6 + 2/3= 90/60 or 1 30/60.

5/6 + 2/3 is larger.

I picked slide number one which is 2/3 + 3/4 and 5/6 + 2/3. To get 2/3 of 1 hour, you have to divide 60 by 3 which is equals to 20. But the denominator of the fraction is 2. That means we need to multiply 20 by 2 which is 40. So the 2/3 of 60 is 40 mins. At 3/4, we have to do the same operations. 60 divided by four is 15 but we need 3 parts of it so we multiply 15 by 3. The answer is 45. So 40 mins. + 45 mins. is equals to 85/60 mins. or 1 hour and 25/60. The other way to show 25/60 is 5/12. So 85 mins. + 40 mins. is = to 125/60 or 2 hours and 5/60 mins.

On the other hand, 5/6 of 60 is 50 mins. To get the answer, you just have to divide 60 by the numerator which is 6. So 60 divided by 6 is = to 10. Since we need five parts of it, we have to multiply 10 by 5 and the answer is 50. 2/3 is equals to 40 minutes. Just do like the same thing as what we did on the first fraction. So 50+40=90. The answer is 90/60 or 1 1/2 hour.

Which one is bigger .. ? 125/60 or 90/60? obviously, the answer is 125 which is 2/3 + 3/4.


Thanks everyone for reading my comment.

hhI choose slide 1 to comment on (2/3 + 3/4 and 5/6 + 2/3)

2/3 + 3/4 - How I did this question is... for 2/3 what I did is 60 (because there is 60 mins in an hour) divided it by 3 (because 3 is the denominator of 2/3) and I got 20 mins. Then I timed it by 2 (because 2 is the numerator of 2/3) which equals 40 mins. Then I added 3/4 which is 45 mins, how I did it was, sorta the same thing, 60 divided by 4 which is 15 then time is by 3 which equals, 45 mins. Add 40 an 45 together and it equals 85 mins or 1 hour and 25 mins.

I did the same thing to 5/6 + 2/3. First 5/6 - 60 divided by 6 which equals 10 then times 5 which equals 50 then add 2/3 which is 40 mins because 60 divided by 3 is 20 then times it by 2 which equals 40. Then add 50 and 40 together and it equals 90 mins or 1 hour and 30 mins.

Btw. 5/6 + 2/3 is bigger then 2/3 + 3/4.

2/3 + 3/4 and 5/6 + 2/3. 2/3 =40 minutes in clock time. 3/4 is 45 minutes in clock time. So all together it equals 1 hour and 25 minutes.
5/6 equals 50 minutes in clock time. 2/3 equals 40 minutes in clock time. All together it equals 1 hour and 30 minutes.
So, 5/6 + 2/3 is larger.
