How do you convert a fraction to a percent?

1. Multiply the fraction by 100

2. Subtract the fraction from 100

3. Add 100 to the fraction

4. Divide the numerator by the denominator

The correct answer is: Multiply the fraction by 100

To convert a fraction to a percent, the proper method involves multiplying the fraction by 100. This process allows you to express the fraction in terms of a percentage, which is a way of comparing the fraction to the whole (100%). Here's how it works: when you have a fraction, for example, 3/4, you would multiply 3/4 by 100 to get its equivalent percent. The calculation is as follows: \[ \frac{3}{4} \times 100 = 75 \] This means that 3/4 is equivalent to 75%. By using this method, you effectively scale the fraction to represent it out of 100 parts, which is what a percent is defined as. This is why multiplying by 100 is the correct approach for converting a fraction to a percent.
