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 9990 by the denominator 9128:
9990 (numerator) ÷ 9128 (denominator) = 1.09
As a result, you get 1.09 as your answer when you convert 9990/9128 to a decimal.
