What is 5/8 as a percent and a decimal
Makovka662 [10]

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 5/8 as a percent, we need to find a fraction equivalent to 5/8 that has a 100 in the denominator. We can do this by setting up a proportion.

\frac{5}{8} = \frac{n}{100}

<h3 /><h3>8n = 500</h3><h3>÷8     ÷8</h3><h3>    n = 62.5%</h3><h3>Therefore, 5/8 is equal to 62.5%.</h3><h3 />

To write a fraction as a decimal, we can simply divide the numerator by the denominator.

5 ÷ 8 = 0.625

Therefore, 5/8 is equal to 0.625.
