Answer: 20%
Step-by-step explanation: To write a fraction as a percent,
first remember that a percent is a ratio of a number to 100.
So to write 1/5 as a percent, we need to find a fraction
equivalent to 1/5 that has a 100 in the denominator.
We can do this by setting up a proportion.
So we have [tex]\frac{1}{5} = \frac{n}{100}[/tex].
Now, we can use cross-products to find the missing value.
So we have (1)(100) = (5)(n).
So we have the equation 100 = 5n.
Next, dividing both sides of the equation by 5, we have 20 = n.
So 1/5 is equal to 20/100 or 20%
Since a percent is a ratio that compares a
number to 100, we can 20/100 as 20%.
