Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).
A ratio table can be described as table that shows equivalent values between two or more numbers and helps us to understand the relationship between the numbers.
The first step is to determine the ratio between the money earned and the money saved.
Ratio = money saved / money earned
8/10 = 0.8
Now, multiply the ratio gotten in the previous step by the amount earned to determine the amount saved.
Amount saved = amount earned x ratio
0.8 x 120 = $96
