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 54 by the denominator 14:
54 (numerator) ÷ 14 (denominator) = 3.86
As a result, you get 3.86 as your answer when you convert 1 40/14 (or 54/14) to a decimal.
