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 70 by the denominator 9:
70 (numerator) ÷ 9 (denominator) = 7.78
As a result, you get 7.78 as your answer when you convert 7 7/9 (or 70/9) to a decimal.
