The first step to changing 3 9/43 into a decimal is to change it to an improper fraction. To do that, we need to multiply 3 by 43 and add its product to 9 in the numerator to get: 138/43. Now we will attempt to convert 138/43 to a decimal using the following method.
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 138 by the denominator 43:
