Math Tutor Explains: What is 130 109/10 as a decimal?

One method to convert 1409/10 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 1409 by the denominator 10:

1409 (numerator) ÷ 10 (denominator) = 140.9

And there you go! We got 140.9 as the answer when you convert 130 109/10 (or 1409/10) to a decimal.

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:

And finally, you get 140.9 as your answer when you convert 130 109/10 (or 1409/10) to a decimal.
