Question

What percent of $5x$ is equal to $x/5$?

Answer 1

Answer:

4%

Step-by-step explanation:

Let y% of 5x is equal to $\frac{x}{5}.$

$y\% \: of \: 5x = \frac{x}{5} \\ \\ \therefore \: \frac{y}{100} \times 5x = \frac{x}{5} \\ \\ \therefore \: y = \frac{x}{5 \times 5x} \times 100 \\ \\ \therefore \: y = \frac{1}{25} \times 100 \\ \\ \therefore \: y = 4 \\ \\ \therefore \: 4\% \: of \: 5x \: is \: equal \: to \: \frac{x}{5}$
