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 86 by the denominator 40:
86 (numerator) ÷ 40 (denominator) = 2.15
As a result, you get 2.15 as your answer when you convert 1 46/40 (or 86/40) to a decimal.
