Answer:
3/4 plus 3/7= 33/28
or simplified would be 1 5/28
Reasoning:
first is to make the bottom of the fractions the same. Both four and seven go into 28. four times seven = 28, which means you multiply the top of 3/4 by 7 = 21. Seven times four = 28, which means you multiply the top of 3/7 by 4 = 12. 21 plus 12 = 33. So 33/28 would be your answer. As a mixed fraction it would be 1 5/28.
