Question

Find two mixed numbers so that the sum is seven wholes and two eights and the difference is two wholes and four eigths

Answer 1

Explanation:

x + y = 7 + 2/8 = 58/8

x - y = 2 + 4/8 = 20/8

Add the equations together

2x = 78/8

x = 39/8

y = x - 20/8 = 19/8

x = 39/8 = 4⅞

y = 19/8 = 2⅜
