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 125 by the denominator 16:
125 (numerator) ÷ 16 (denominator) = 7.81
As a result, you get 7.81 as your answer when you convert 5 45/16 (or 125/16) to a decimal.
