The first step to changing 1 18/40 into a decimal is to change it to an improper fraction. To do that, we need to multiply 1 by 40 and add its product to 18 in the numerator to get: 58/40. Now we will attempt to convert 58/40 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 58 by the denominator 40:
58 (numerator) ÷ 40 (denominator) = 1.45
As a result, you get 1.45 as your answer when you convert 1 18/40 (or 58/40) to a decimal.
