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 30 by the denominator 7:
30 (numerator) ÷ 7 (denominator) = 4.29
As a result, you get 4.29 as your answer when you convert 4 2/7 (or 30/7) to a decimal.
