I have write the number to a fraction.

1/8.

Would it be .08% or 12.5 %

12.5%

To convert a decimal into a fraction, you can follow these steps:

1. Write down the decimal number as the numerator (the top number).
2. Determine the denominator (the bottom number) by using the following rule: For decimal places, write the number 1 followed by the same number of zeros as there are decimal places.

In the case of 1/8:

1. The decimal number is 0.125.
2. There are three decimal places, so the denominator will be 10^3, which is 1000.

Therefore, the fraction equivalent of 0.125 is 1/8.
