Step-by-step explanation:

$\frac{7}{8}-\frac{9}{12} ?\frac{1}{8}$

We need to find a common denominator for the two

which will be 24

But we need to multiply the numerators as well to change them.

$\frac{7}{8}(\frac{3}{3})-\frac{9}{12} (\frac{2}{2} )?\frac{1}{8}\\\frac{21}{24}-\frac{18}{24}? \frac{1}{8}\\\frac{3}{24} ?\frac{1}{8}\\Simplify\\\frac{1}{8} =\frac{1}{8}$
