what are the three ways to express ratios

Answer 1

There are three common ways to express ratios:

1. Using the word "to" or a colon ":" to separate the two numbers in the ratio. For example, a ratio of 2:3 means that for every two of one quantity, there are three of another.

2. Using a fraction to express the ratio. For example, a ratio of 3:4 can be written as 3/4.

3. Using the word "per" to express the ratio. This is common when talking about rates or rates per unit. For example, a ratio of 5:7 can be expressed as "5 per 7".
