Question: 1 / 400

How can you convert a fraction to a percentage?

Add 50 to the numerator

Multiply the fraction by 100

To convert a fraction to a percentage, you can multiply the fraction by 100. This process works because a percentage represents a part per hundred. For example, if you have the fraction 3/4, multiplying it by 100 gives you 75. This is because 3 divided by 4 equals 0.75, and when you multiply 0.75 by 100, you arrive at 75%. Therefore, this method effectively transforms the fraction into a percentage form, making it more intuitive to understand in terms of parts of a whole.

The other options do not accurately achieve this result. Adding a number to the numerator or subtracting from the fraction does not correspond to the mathematical operation required for conversion into percentage form, nor does dividing the fraction by any number correctly express its value in percentage terms.
