Question

Write each fraction as a sum or difference 2m-5/9

Answer 1

This is a fraction that has a linear expression as the numerator and a constant number in denominator.
So we can simply divide each term of numerator by denominator because we can write $\frac{a+b}{c} = \frac{a}{c}+ \frac{b}{c}$
So we can write given fraction as
$\frac{2m-5}{9} = \frac{2m}{9} - \frac{5}{9}$ which is expressed as a difference.
