A fraction is written in terms of two parts: the number on top is called the numerator and the number on the bottom is called the denominator. We can use the division method to solve this question. To get a decimal, simply divide the numerator 55 by the denominator 15:
55 (numerator) ÷ 15 (denominator) = 3.67
As a result, you get 3.67 as your answer when you convert 3 10/15 (or 55/15) to a decimal.
