A fraction is usually split into two parts: the first part is the number on top, called the numerator; and the second part is the number on the bottom, called the denominator. These are both separated by a line called the “divisor line”. We can use the division method help to solve this question: to get a decimal, simply divide the numerator 7830 by the denominator 150 (which you can enter in any calculator):
7830 (numerator) ÷ 150 (denominator) = 52.2
And finally, you get 52.2 as your answer when you convert 52 30/150 (or 7830/150) to a decimal.
