Math Tutor Solution: 1 11/10 as a decimal is 2.1
Methods
First step – Making the fraction improper:
The first step to changing 1 11/10 into a decimal is to change it to an improper fraction. To do that, we need to multiply 1 by 10 and add its product to 11 in the numerator to get: 21/10. Now we will attempt to convert 21/10 to a decimal using one of the following methods:
Method 1 from a math tutor – Explanation using the division method:
One method to convert 21/10 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 21 by the denominator 10:
21 (numerator) ÷ 10 (denominator) = 2.1
And there you go! We got 2.1 as the answer when you convert 1 11/10 (or 21/10) to a decimal.
Method 2 from a math tutor – 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 10 a power of 10, we need to multiply by 1 (10 * 1 = 10. Since we multiplied the denominator by 1, we also need to multiply the numerator by 1 too:
