How to Get a Ratio to a Fraction

Ratios and fractions are often used in measurements.

A ratio is a mathematical term denoting a pair of numbers or values that are being compared. A fraction is similar to a ratio because it also contains two numbers that share a relationship. In fact, ratios are often written in fraction form. Converting a ratio to a fraction requires making minor changes to the manner in which the numbers within the fraction are expressed.

Instructions

1. Write the first number of the ratio. This will be the numerator of the fraction.

2. Insert a fraction bar, which can be placed underneath or to the right of the numerator.

3. Write the second number of the ratio, which will serve as the denominator of the fraction.

4. Reduce the fraction to simplest terms if necessary. For example, if the original ratio is 4:10, you would write the fraction 4/10. Then you can reduce the fraction by dividing both numbers by 2, which would leave the simplified form of 2/5.
