In mathematics, fractions are used to represent a part of a whole. They consist of a numerator (the top number) and a denominator (the bottom number). The number 48 can be expressed as a fraction in simplest form by finding the greatest common divisor (GCD) of the numerator and the denominator and dividing both by it.
Let's start by expressing 48 as a fraction:
48 can be written as 48/1, since any number divided by 1 is itself.
However, we can simplify this fraction further by finding the factors of 48 and the greatest common divisor (GCD) between 48 and 1.
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
The GCD of 48 and 1 is 1.
Since the GCD is 1, we cannot simplify the fraction 48/1 any further. Therefore, 48 as a fraction in simplest form is:
48/1
Or simply:
48
This is because any number divided by 1 is itself, and 48 is already in its simplest form.
However, if we want to express 48 as a fraction with a denominator other than 1, we can do so by finding the factors of 48 and creating a fraction. For example:
48 = 24 x 2
So, we can express 48 as:
48/1 = 24/2
This fraction is also in simplest form, since the GCD of 24 and 2 is 2.
Other examples of fractions with 48 as the numerator include:
48/3 = 16 48/4 = 12 48/6 = 8 48/8 = 6 48/12 = 4 48/16 = 3 48/24 = 2
Note that these fractions are not necessarily in simplest form, and may require further simplification.

How can we apply the concept of fractions in real-life scenarios?
Fractions have numerous applications in real-life scenarios, including:
- Cooking: Fractions are used to represent ingredient ratios in recipes.
- Science: Fractions are used to represent proportions and ratios in scientific calculations.
- Finance: Fractions are used to represent interest rates and investment returns.
- Engineering: Fractions are used to represent proportions and ratios in design calculations.
Example 1: Cooking
When following a recipe, you may need to adjust the ingredient quantities based on the number of servings. Fractions can be used to represent the ingredient ratios. For example:
1 1/2 cups of flour
In this example, the fraction 1 1/2 represents the ratio of flour to other ingredients.
Example 2: Science
In scientific calculations, fractions can be used to represent proportions and ratios. For example:
The ratio of hydrogen to oxygen in water is 2:1.
In this example, the fraction 2/1 represents the ratio of hydrogen to oxygen.
Example 3: Finance
In finance, fractions can be used to represent interest rates and investment returns. For example:
A savings account earns an annual interest rate of 2.5%.
In this example, the fraction 2.5/100 represents the interest rate.
Example 4: Engineering
In engineering design calculations, fractions can be used to represent proportions and ratios. For example:
The ratio of the width to the length of a beam is 1:3.
In this example, the fraction 1/3 represents the ratio of the width to the length.
By understanding and applying the concept of fractions, we can solve problems and make calculations more efficient in various fields.
