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 34 by the denominator 2:
34 (numerator) ÷ 2 (denominator) = 17
As a result, you get 17 as your answer when you convert 12 10/2 (or 34/2) to a decimal.
