Answer:

20%

Explanation:

Step 1: Start by changing the fraction to a decimal by diving the numerator by the denominator (1 divided by 5). That equals 0.2.

Step 2: Change the decimal to a percent by multiplying it by 100%, or moving the decimal two places. That gives you 20%.

Another way of thinking about it is multiplying the numerator by 100%, then dividing that by the denominator (100% divided by 5). This gives you 20%.
