Write $\frac{5}{8}$ as a decimal.
To write a fraction as a decimal, I can divide the numerator by the denominator. So, $\frac{5}{8}$ is the same as $5 \times \frac{1}{8}$. I know that $\frac{1}{8}$ is the same as $0.125$, since I can divide 1 by 8 using long division. Therefore, $5 \times 0.125 = 0.625$. This is the decimal equivalent of $\frac{5}{8}$.
