Convert 0.45 To A Fraction In Simplest Form

Quick Links :

Converting a decimal to a fraction is a simple process that involves finding the equivalent fraction in its simplest form.

Understanding Decimals and Fractions

Before we dive into the conversion process, let's quickly review what decimals and fractions are. A decimal is a way of expressing a number using a point (.) to separate the whole part from the fractional part. For example, 0.45 is a decimal number where 0 is the whole part and 0.45 is the fractional part.

On the other hand, a fraction is a way of expressing a number as a ratio of two integers. For example, 9/20 is a fraction where 9 is the numerator and 20 is the denominator.

Converting 0.45 to a Fraction

To convert 0.45 to a fraction, we can use the following steps:

1. We can write 0.45 as 45/100, since there are two decimal places.
2. We can then simplify the fraction by dividing both the numerator and denominator by 5.
3. This gives us 9/20, which is the simplest form of the fraction.

Therefore, 0.45 can be converted to a fraction in its simplest form as 9/20.

Why is 9/20 the Simplest Form?

To ensure that 9/20 is indeed the simplest form of the fraction, we need to check if the numerator and denominator have any common factors. In this case, 9 and 20 do not have any common factors other than 1, which means that the fraction is in its simplest form.

Benefits of Converting Decimals to Fractions

Converting decimals to fractions has several benefits, especially in mathematical calculations and real-world applications. Some of the benefits include:

• Simplifying calculations: Fractions can be easier to work with than decimals, especially when performing arithmetic operations.
