Question

reduce to simplest form.
-\frac{1}{2}-\frac{2}{5}=\square

Explanation:

Step1: Find common denominator

The common denominator of 2 and 5 is 10. So, $-\frac{1}{2}=-\frac{1\times5}{2\times5}=-\frac{5}{10}$ and $-\frac{2}{5}=-\frac{2\times2}{5\times2}=-\frac{4}{10}$.

Step2: Subtract the fractions

$-\frac{5}{10}-\frac{4}{10}=-\frac{5 + 4}{10}=-\frac{9}{10}$

Answer:

$-\frac{9}{10}$
