What is 112 38/1 as a decimal?

Accepted Solution

Solution: 112 38/1 as a decimal is 150MethodsFirst step – Making the fraction improper:The first step to changing 112 38/1 into a decimal is to change it to an improper fraction. To do that, we need to multiply 112 by 1 and add its product to 38 in the numerator to get: 150/1. Now we will attempt to convert 150/1 to a decimal using one of the following methods:Method 1 – Explanation using the division method: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 150 by the denominator 1 (which you can enter in any calculator):150 (numerator) ÷ 1 (denominator) = 150And finally, you get 150 as your answer when you convert 112 38/1 (or 150/1) to a decimal.Method 2 – Explanation using the factors of 10 method:Sometimes, dividing a number by a power of 10 (like 10, 100, 1000 etc.) is easy because all you need to do is move the invisible decimal place left by how many zeros you have in the power of 10. But for this question, the denominator, 1, isn’t a power of 10.However, we can change the fraction: if the denominator is a factor of a power of 10, like 2, 4, 5, 8, 10, 16, 20, 25, 40, 50 and so on, then we can convert the fraction into one that is easy to calculate.To do this, we need to make the denominator to a power of 10 - to make 1 a power of 10, we need to multiply by 10 (1 * 10 = 10). We multiplied the denominator by 10, so now we need to also multiply the numerator by 10 too:150∗101∗10=150010=150\frac{150 * 10}{1 * 10} = \frac{1500}{10} = 1501∗10150∗10​=101500​=150And finally, you get 150 as your answer when you convert 112 38/1 (or 150/1) to a decimal.Practice more conversion problemsAll it takes to be better at something is some practice!
