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 100 by the denominator 7:
100 (numerator) ÷ 7 (denominator) = 14.29
As a result, you get 14.29 as your answer when you convert 13 9/7 (or 100/7) to a decimal.
