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 216 by the denominator 310:
216 (numerator) ÷ 310 (denominator) = 0.7
As a result, you get 0.7 as your answer when you convert 216/310 to a decimal.
