The first step to changing 2 42/20 into a decimal is to change it to an improper fraction. To do that, we need to multiply 2 by 20 and add its product to 42 in the numerator to get: 82/20. Now we will attempt to convert 82/20 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 82 by the denominator 20:
82 (numerator) ÷ 20 (denominator) = 4.1
As a result, you get 4.1 as your answer when you convert 2 42/20 (or 82/20) to a decimal.
