Question

multiply:
\frac{1}{5} * 4
provide an answer as a simplified fraction or mixed number.

Explanation:

Step1: Recall fraction multiplication rule

To multiply a fraction by an integer, we multiply the numerator of the fraction by the integer and keep the denominator the same. So for $\frac{1}{5} \times 4$, we have $\frac{1\times4}{5}$.

Step2: Calculate the numerator

$1\times4 = 4$, so the result is $\frac{4}{5}$. Since 4 and 5 have no common factors other than 1, the fraction is already in its simplest form.

Answer:

$\frac{4}{5}$
