$-dfrac{3}{8} + dfrac{1}{2}$
write your answer in simplest form.
\boxed{}

Explanation:

Step1: Find a common denominator

The denominators are 8 and 2. The least common denominator is 8. Rewrite $\frac{1}{2}$ with denominator 8: $\frac{1}{2}=\frac{1\times4}{2\times4}=\frac{4}{8}$.

Step2: Add the fractions

Now we have $-\frac{3}{8}+\frac{4}{8}$. Add the numerators: $-3 + 4 = 1$. So the result is $\frac{1}{8}$.

Answer:

$\frac{1}{8}$
