Math Exam Review Slide 23

Adding and Subtracting Fractions
















So the question is 1/2+1/2 = 2/2, but that isn't good enough because you have to always simplify when it can be simplified. So its 1/1 then 1 whole. First you always check for common denominators. If your fractions have the same denominator you leave them the same and just add the numerators.

Subtracting















The question was 3/4 - 1/4=2/4=1/2. ( make sure you don't forget to simplify.) First you check for common denominators. In this question they are the same so just take away the two numerators.

Try these questions to help you practice :).

2/3+4/5=
6/7+2/8=
2/3-1/3=
4/5- 2/5=

Answers...

1. the common denominator is 15. So whatever you did to get 15 u do to the numerators. So 2x5=10 so its 10/3, then 4x3= 12 so its 12/5. So 10+12 = 22 and the denominators stay at 15. Its 22/15. Now you have to simplify it to 1 whole and 7/15.

Since I already told you how to do this I'm just gonna give you the answers now.

2. 1 whole and 3 /28

3.1/3

4. 2/5
