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:**

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**
