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 27 by the denominator 7:
27 (numerator) ÷ 7 (denominator) = 3.86
As a result, you get 3.86 as your answer when you convert 1 20/7 (or 27/7) to a decimal.
