How can you express 1/4 as a percent?
Sever21 [200]

Answer: 25%

Step-by-step explanation: 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 1/4 as a percent, we need to find a fraction equivalent to 1/4 with a 100 in the denominator. We can do this by setting up a proportion.

\frac{1}{4} = \frac{n}{100}

4n = 100

÷4    ÷4

 n = 25

Therefore, 1/4 is equivalent to 25%.
