For sure.

Answer 2

Im getting c as a different answer and b should be reduced to 3/10.... :)
b.(3/4÷ 9/2)= 1/6; (1/2(3/5-1/3))=2/15... so (1/6)+(2/15)= 3/10

c. (8/5÷ 5/4)=32/25; (7/2+7/5)=49/10.....so (32/25)÷ (49/10)=64/245

Answer 3

The sum of shows for you to upload the fractions. substitute to wrong fractions first. 22/5 + ninety one/15 you are able to not upload fractions with diverse denominators, so convert the 1st to /15. To get 15 on the backside you need to multiply the 5 by utilising 3, so multiply the precise by utilising 3 too, and additionally you get sixty six/15. you are able to now upload the two fractions. so which you have sixty six/15 + ninety one/15.
