Question

What should be subtracted from (5/6 - 7/8) to get 1/2?

Answer 1

the answer of the question (5/6-7/8) to get 1/2 is -2/40

Answer 2

$( \frac{5}{6} - \frac{7}{8} ) \\ lcm \: of \: 6 \: and \: 8 = 24 \\ \frac{20 - 21}{24} = - \frac{1}{24} \\ - \frac{1}{24} + \frac{1}{2} \\ lcm \: of \: 2 \: and \: 24 \\ \frac{11}{24}$

therefore 11/24 should be subtracted from (5/6 - 7/8) to get 1/2
