When it comes to expressing numbers as fractions, there are often multiple ways to do so. The number 45 is no exception. In this article, we will explore three different ways to write 45 as a fraction.

What is a Fraction?

Before we dive into the different ways to write 45 as a fraction, let's quickly review what a fraction is. A fraction is a way to express a part of a whole as a ratio of two numbers. The top number, called the numerator, represents the part, while the bottom number, called the denominator, represents the whole.

Method 1: Writing 45 as a Fraction with a Denominator of 1

One way to write 45 as a fraction is to use a denominator of 1. This may seem obvious, but it's a valid way to express 45 as a fraction. When we write 45 as a fraction with a denominator of 1, it looks like this:

45/1

This fraction tells us that we have 45 parts out of a total of 1 part. Since we have the entire part, the fraction is equal to the whole number 45.

Example:

Suppose we have 45 cookies and we want to express this as a fraction of the total number of cookies. If we have a total of 1 batch of cookies, we can write the fraction as 45/1.

Method 2: Writing 45 as a Fraction with a Denominator of 5

Another way to write 45 as a fraction is to use a denominator of 5. To do this, we need to find the greatest common divisor (GCD) of 45 and 5. The GCD is 5, so we can divide both numbers by 5 to get:

45 ÷ 5 = 9 5 ÷ 5 = 1

So, we can write 45 as a fraction with a denominator of 5 like this:

9/1 = 45/5

This fraction tells us that we have 9 groups of 5 parts each, which is equal to the whole number 45.

Example:

Suppose we have 45 students in a class and we want to divide them into groups of 5. We can write the fraction as 45/5, which tells us that we have 9 groups of 5 students each.

Method 3: Writing 45 as a Fraction with a Denominator of 9

Finally, we can write 45 as a fraction with a denominator of 9. To do this, we need to find the GCD of 45 and 9. The GCD is 9, so we can divide both numbers by 9 to get:

45 ÷ 9 = 5 9 ÷ 9 = 1

So, we can write 45 as a fraction with a denominator of 9 like this:

5/1 = 45/9

This fraction tells us that we have 5 groups of 9 parts each, which is equal to the whole number 45.

Example:

Suppose we have 45 boxes of crayons and we want to pack them into cartons of 9 boxes each. We can write the fraction as 45/9, which tells us that we have 5 cartons of 9 boxes each.

Conclusion and Next Steps
