Converting 2 2/5 to an Improper Fraction: A Step-by-Step Guide

This article will guide you through the process of converting the mixed number 2 2/5 into an improper fraction. Understanding this conversion is crucial for various mathematical operations and is a fundamental concept in fractions. We'll break down the steps clearly and simply, making it easy for anyone to understand, regardless of their math background.

What is a Mixed Number?

A mixed number combines a whole number and a fraction, like 2 2/5. It represents a value greater than one.

What is an Improper Fraction?

An improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number). For example, 12/5 is an improper fraction.

Converting 2 2/5 to an Improper Fraction

Here's the step-by-step process to convert 2 2/5 into an improper fraction:

Step 1: Multiply the whole number by the denominator.

In our example, the whole number is 2 and the denominator is 5. So, we multiply 2 x 5 = 10.

Step 2: Add the numerator to the result from Step 1.

The numerator is 2. Adding this to the result from Step 1 (10), we get 10 + 2 = 12.

Step 3: Keep the same denominator.

The denominator remains unchanged. In this case, the denominator is 5.

Step 4: Write the improper fraction.

Combine the results from Step 2 and Step 3 to form the improper fraction. Therefore, 2 2/5 converted to an improper fraction is 12/5.
