Set up problem then find the sum simplify 3/7 +1/4
Answered by Steve
use a common denominator. Then you have

12/28 + 7/28

not so hard now, eh?
Answered by Ms. Sue
3/7 +1/4

Multiples of 7: 7, 14, 21, 28
Multiples of 4: 4, 8, 12, 16, 20, 24, 28

So the common denominator is 28
28 / 7 = 4
4 * 3 = 12
So -- 3/7 = 12/28

(12/28) + (7/28) = 19/28
