What is 19 1/8 as a decimal?

There are different ways to represent the same number: fractions, decimals, and even percentages. In this particular guide, let’s explore how we can use the division method to convert 19 1/8 to a decimal.

Solution: 19 1/8 as a decimal is 19.12

Methods

First step – Making the fraction improper:

The first step to changing 19 1/8 into a decimal is to change it to an improper fraction. To do that, we need to multiply 19 by 8 and add its product to 1 in the numerator to get: 153/8. Now we will attempt to convert 153/8 to a decimal using one of the following methods:

Method 1 – Explanation using the division method:

One method to convert 153/8 to a decimal is by using the division method. Before we move ahead to the method, here is a quick recap on fractions: A fraction is a number representation that is broken down into two parts - the number on top is called the numerator, and the number on the bottom is called the denominator. To get a decimal using the division method, simply divide the numerator 153 by the denominator 8:

153 (numerator) ÷ 8 (denominator) = 19.12

And there you go! We got 19.12 as the answer when you convert 19 1/8 (or 153/8) to a decimal.

Method 2 – Explanation using the factors of 10 method:

In this method, we will convert the denominator into a power of 10 and then our fraction will be easier to calculate. 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 it into a power of 10.

In order to make 8 a power of 10, we need to multiply by 125 (8 * 125 = 1000. Since we multiplied the denominator by 125, we also need to multiply the numerator by 125 too:

$\frac{153 * 125}{8 * 125} = \frac{19125}{1000} = 19.12$

And finally, you get 19.12 as your answer when you convert 19 1/8 (or 153/8) to a decimal. 8 Math Hacks and Tricks to Turn Your ‘Okay’ Math Student Into a Math Champion!
