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 45 by the denominator 8:
45 (numerator) ÷ 8 (denominator) = 5.63
As a result, you get 5.63 as your answer when you convert 5 5/8 (or 45/8) to a decimal.
