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 59 by the denominator 21:
59 (numerator) ÷ 21 (denominator) = 2.81
As a result, you get 2.81 as your answer when you convert 1 38/21 (or 59/21) to a decimal.
