Answer:
120cm = 46.8 inches
Explanation:
This can be solved as a rule of three problem.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
Unit conversion problems, like this one, is an example of a direct relationship between measures.
Each cm has 0.39 inches. How many inches are there in 120 cm?
1cm - 0.39inches
120cm - x inches
inches
120cm = 46.8 inches
