Chelsey's First Growing Post









Which is Larger 1/2 + 1/6 or 1/4 + 7/12??




1/4 + 7/12!!!!


What I did: 1/2+1/6

(60÷2=30.........1/2 of 60=30min.)

(60÷6=10..........1/6 of 60=10min.)

(30+10=40)

What I did: 1/4+7/12

(60÷4=15..........1/4 of 60=15min.)

(60÷12=5.....7x5=35.....7/12 of 60=35min.)

(35+15=50)<---- LARGER!!



Chelseey aaand myaa's Bikerace!


























6. http://www.gamequarium.com/fractions.html I found this in google and you can choose from
playing games about changing fractions and comparing unlike fractions and etc.

7. When we did the bikerace project I used division, for the twelfth, sixth and a third I remember dividing the number by 60 and getting my answer.

8. To get 1/4 of 16 you would have to divide 16 by 4 to get 4, or you could cut the fraction in half (8) then cut those in half to get four pieces of 4. // To get 3/4 of 16 you would divide 16 by 4 to get 4. Then times that by 3 to get 12. You could also cut 16 in half (8) then cut one half in half(4) and leave one as 8 making it equal 12.

9. 1/2 + 1/3 does not equal 2/5.
How Did I Get That....
At first I thought 1/2 + 1/3 did equal 2/5 because I didn't no how to add fractions so i thought you added it like that. But now i no you would have to change the denominator to the number that both 3 and 2 go into equally which would be 6 . I no now that whatever you do to one side you have to do to the other. So if i times 2 x 3 to get it to equal 6 then i have to times the numerator 1 x 2 also to get the numerator to equal 2. Then if i had to times 2 x 3 to get it to 6 then i have to times the numerator by 3 also to get it to equal 3. So then in the end you get
2/6 + 3/6 = 5/6
so now I seethe answer is not 2/5 it is 5/6!!
