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 306 by the denominator 420:
306 (numerator) ÷ 420 (denominator) = 0.73
As a result, you get 0.73 as your answer when you convert 306/420 to a decimal.
