To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write \(\frac{1}{8}\) as a percent, we need to find a fraction equivalent to \(\frac{1}{8}\) that has a 100 in the denominator. We can do this by setting up a proportion.
\(\frac{1}{8}\) = \(\frac{n}{100}\)
Now, we can use cross products to find the missing value.
8n = 100
÷8 ÷8 ← divide by 8 on both sides
n = 12.5
Therefore, \(\frac{1}{8}\) is equal to \(\frac{12.5}{100}\) or 12.5%.
