## Subtracting Fractions: 1 1/4 - 1/2

This article will guide you through the process of subtracting the fractions 1 1/4 and 1/2.

### Understanding Mixed Numbers

First, let's understand what a **mixed number** is. A mixed number combines a whole number and a fraction. In our case, 1 1/4 represents one whole unit plus one-quarter.

### Finding a Common Denominator

Before we can subtract fractions, they need to have the same denominator. The least common denominator (LCD) for 4 and 2 is 4.

**1 1/4 remains the same**as the denominator is already 4.**1/2 is multiplied by 2/2**to get 2/4.

### Performing the Subtraction

Now we have:

- 1 1/4 - 2/4

Since we're dealing with a mixed number, we'll subtract the fractions first.

- 1/4 - 2/4 = -1/4

Since the result is a negative fraction, we need to borrow from the whole number part.

- 1 - 1/4 = 3/4

Therefore, **1 1/4 - 1/2 = 3/4**.
