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 3 by the denominator 87:
3 (numerator) ÷ 87 (denominator) = 0.03
As a result, you get 0.03 as your answer when you convert 3/87 to a decimal.
