<h3>What is a ratio?</h3>
It is important to note that a ratio demonstrates how many times one number can fit into another number as they contrast two numbers by ordinarily dividing them.
In this case, the heights of the dolls are given in the ratio 7: 11: 13
Based on the information, the ratio will be illustrated thus:
7/7 = 1
11/7 = 1.57
13/7 = 1.86
This illustrates the ratio of the dolls.
