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 5141 by the denominator 145 (which you can enter in any calculator):
5141 (numerator) ÷ 145 (denominator) = 35.46
And finally, you get 35.46 as your answer when you convert 35 66/145 (or 5141/145) to a decimal.
