### Karen's Scribe

Last Friday in class we did a test about adding and subtracting fractions.
I will be explaining two questions from the test. The following questions will be #'s 3&4.
Question #3

To find the answer I used \$ strategy. First I ignored the 5 from 5 9/10 then I have to figure out the answer for 9/10 using 100, so then it would be 100÷10(denominator)=10 multiply by 9(numerator) equals 9o it would be 90/100. Next is 3 4/5 again I ignored 3 so then for now we have 4/5, 100 divided by 5 is 20 multiply by 4 is equals 80/100.

Now we have 10/100, we still have 5 and 3 that we ignored previously. I just did 5-3 = 2 then included 2 to the answer

Question #4

Using the \$ money strategy. I did kind of the same thing for the question #3 that I just answered previously. I also ignored the whole for each fraction so then for now I have 2/5 and 13/20

But since you can't subtract 40/100 to 65/100. Now I have to take the whole from 5 9/10 to subtract it to 1 ( 5-1) = 4 then I add 40 + 100 since we have 40/100 I added them together so it became 140/100for 3 65/100 I just leave it the same way then now we have 4 140/100 subtract by 3 65/100 = 1 75/100 although we can still simplify it.

I simplified 75/100 divided by 5 = 15/20 then again divided by 5 = 3/4 then that's where I added 1 to get 1 3/4
