# How to write a ratio as a simplified fraction

For example, comparing dogs and cats, boys and girls, or students and teachers can all be turned into a ratio or fraction, in which there is a numerator and a denominator. First, find the denominator.

To convert, start by adding both parts of the ratio together. A ratio can be a part-to-whole or a part-to-part ratio, and the methods for converting each are a little different.

Part A of the ratio is the numerator and part B is the denominator. Thirdly, write down the denominator, or bottom number.

## How to write a ratio as a simplified fraction

The ratio can also be written as "1 to 2. How to Convert a Part-to-Whole Ratio to a Fraction A part-to-whole ratio is an expression of the relationship between a subset and the entire set. For example, comparing dogs and cats, boys and girls, or students and teachers can all be turned into a ratio or fraction, in which there is a numerator and a denominator. To convert a part-to-whole ratio to a fraction, simply rewrite the ratio as a fraction. Thirdly, write down the denominator, or bottom number. The fraction can optionally be reduced after converting, if needed. Convert your ratios to fractions by replacing the "colon" symbol with a "divide" symbol. Updated March 09, By Charlotte Johnson Fractions consist of sets of numbers in which the top number numerator illustrates a part that is related to the whole unit, which is represented by the bottom number denominator. Then, for each part of the ratio, create a fraction with the numerator being the first part of the ratio and the denominator being the sum that was just found. To convert a fraction to a ratio, first write down the numerator, or top number. This will be the denominator for each of the fractions and also represents the whole set. Simplify your fraction by dividing the top and bottom by the same number until you cannot divide any longer. Second, write a colon. The ratio between pepperoni and non-pepperoni slices is

You can then divide both numbers by 5 to get a simplified ratio of The result will be two fractions that represent the proportion of the subset to the whole set.

The ratio can also be written as "1 to 2. Reducing Ratios If necessary, you can reduce the ratio after converting it from a fraction. She has contributed to a variety of websites, specializing in health, education, the arts, home and garden, animals and parenting.

Change any worded ratios, such as "one of two" or "one to two," into numerical ratios.
