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 133 by the denominator 43:
133 (numerator) ÷ 43 (denominator) = 3.09
As a result, you get 3.09 as your answer when you convert 1 90/43 (or 133/43) to a decimal.
