20.9 as a Fraction

Professor Greenline Explaining Math Concepts

Numbers can be categorized into different types. Fractions are one such type. A fraction is always represented in the form of p/q, where p is the numerator and q is the denominator. Fractions represent a whole and a fractional part. Decimals represent the fractional part of numbers. For example, 1/2; numbers in decimal are expressed with a decimal point (.), for example, 20.9. We are going to learn how to convert a decimal to a fraction.

20.9 as a fraction

 

Answer

 

The answer for 20.9 as a fraction will be 209/10.

 

Explanation

 

Converting a decimal to a fraction is a task that can be done easily by following these steps:

 

Step 1: Firstly, express the decimal number as a fraction by using 1 as the denominator. Here, 20.9 becomes 20.9/1.

 

Step 2: To remove the decimal, multiply both the numerator and the denominator by 10 (since there is only 1 decimal place). 20.9/1 × 10/10 = 209/10

 

Therefore, 20.9 can be written as a fraction 209/10.
