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 78 by the denominator 22:
78 (numerator) ÷ 22 (denominator) = 3.55
As a result, you get 3.55 as your answer when you convert 1 56/22 (or 78/22) to a decimal.
