Answer:
4%
Step-by-step explanation:
Let y% of 5x is equal to [tex] \frac{x}{5}. [/tex]
[tex]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} [/tex]
