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 58 by the denominator 4:
58 (numerator) ÷ 4 (denominator) = 14.5
As a result, you get 14.5 as your answer when you convert 12 10/4 (or 58/4) to a decimal.
