Before learning how to convert ratio to fractions, lets define a ratio. A ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. Most of the time we use the punctuation sign colon(:) to separate the values.

While a fraction represents part of the whole thing.

**Formula to Convert Ratio to Fractions.**

To convert a ratio to a fraction follow the following steps.

- Use the sum of both numbers making up the ratio as the denominator:
- Use each of the ratio terms as the numerator in a fraction:
- Reduce each fraction to lowest terms:

**Example 1:**

Convert 2:6 into a fraction.

We begin by summation.

**= 2 + 6**

**= 8**

Therefore, 8 is our denominator.

Then we use each of the ratio terms as numerators.

**= ^{2}/_{8} and ^{6}/**

_{8}

And lastly we simplify the fractions to get.

**= ^{1}/_{4} and ^{3}/_{4}**

**Example 2:**

Convert 1:2 into a fraction.

We begin by adding the two digits.

**= 1 + 2**

**= 3**

The answer becomes the denominator.

Then we use each of the ratio terms as numerators.

Therefore, we get ** ^{1}/_{3}** and

**they are in their simplest form, there is no need to simplify.**

^{2}/_{3}
