## Introduction

0.9 as a fraction is 9/10. In other words, it is one tenth with nine parts. To convert a decimal such as 0.9 to a fraction, we find the place value of each number after the decimal point.

## What is 0.9 as a Fraction?

0.9 can be written as a fraction in a couple different ways. The first way is to write it as 9/10. This can be done because when a decimal is moved to the right, the place value of that number increases by a power of 10. So, 0.9 becomes 9/10. Another way to write 0.9 as a fraction is to use a mixed number. This would be 1 and 4/10, which can be simplified to 9/10.

## Decimals and Fractions

When we see a decimal like 0.9, we can think of it as a fraction. In this case, it is 9 tenths or 9 over 10. We can simplify fractions by cancelling out factors that appear in both the numerator and denominator. For example, 9 over 10 can be simplified to 3 over 5 because they both have a common factor of 3:

0.9 = 9/10 = (3 × 3)/(5 × 3) = 3/5

## The Relationship between Decimals and Fractions

0.9 as a fraction is 9/10. In other words, 9 parts out of 10.

This is because when we divide something into 10 equal parts, each part is worth 1/10. So if we have 9 parts out of 10, that means each part is worth 9/10.

## Converting Decimals to Fractions

To convert a decimal to a fraction, you need to place the decimal point in the numerator (top number) and leave the denominator (bottom number) as 1. For example, if you want to convert 0.9 to a fraction, you would write it like this:

0.9= 9/10

This means that 0.9 is equal to 9/10.

## Conclusion

To sum it up, 0.9 as a fraction is 9/10.
