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 42 by the denominator 5:
42 (numerator) ÷ 5 (denominator) = 8.4
As a result, you get 8.4 as your answer when you convert 6 12/5 (or 42/5) to a decimal.
