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 342 by the denominator 812:
342 (numerator) ÷ 812 (denominator) = 0.42
As a result, you get 0.42 as your answer when you convert 342/812 to a decimal.
