Oct 13, 2025 by wbrum.org 36 views

Introduction

Fractions are a fundamental concept in mathematics, and simplifying them is an essential skill to master. In this article, we will focus on rewriting the division expression as a fraction, specifically the example $\frac{920}{8}$ . We will break down the process into manageable steps, making it easy to understand and apply.

What is a Fraction?

A fraction is a way to represent a part of a whole. It consists of two parts: the numerator (the top number) and the denominator (the bottom number). The numerator tells us how many equal parts we have, while the denominator tells us how many parts the whole is divided into.

Rewriting Division as a Fraction

To rewrite a division expression as a fraction, we need to follow these steps:

Step 1: Write the Division Expression

Start by writing the division expression in the form of a fraction. For example, if we want to rewrite the division expression $\frac{920}{8}$ , we can write it as:

\frac{920}{8}

Step 2: Simplify the Fraction

To simplify the fraction, we need to find the greatest common divisor (GCD) of the numerator and the denominator. The GCD is the largest number that divides both numbers without leaving a remainder.

Step 3: Divide the Numerator and Denominator by the GCD

Once we have found the GCD, we can divide both the numerator and the denominator by the GCD to simplify the fraction.

Step 4: Write the Simplified Fraction

After simplifying the fraction, we can write it in its simplest form.

Simplifying the Example

Let's apply the steps to the example $\frac{920}{8}$ .

Step 1: Write the Division Expression

\frac{920}{8}

Step 2: Simplify the Fraction

To simplify the fraction, we need to find the GCD of 920 and 8. The GCD of 920 and 8 is 4.

Step 3: Divide the Numerator and Denominator by the GCD

We can divide both the numerator and the denominator by 4 to simplify the fraction:

\frac{920}{8} = \frac{920 \div 4}{8 \div 4} = \frac{230}{2}

Step 4: Write the Simplified Fraction

The simplified fraction is $\frac{230}{2}$ .

Conclusion

Rewriting a division expression as a fraction is a straightforward process that involves simplifying the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator. By following the steps outlined in this article, you can simplify fractions with ease. Remember to always simplify fractions to their simplest form to make calculations easier.
