Fractions Addition and Subtraction

Welcome to our guide on fractions addition and subtraction, created for students, teachers, and parents. Here, we will break down the essential ideas of fractions, how to add and subtract them, and provide helpful tips to make learning enjoyable.

What are Fractions?

A fraction shows a part of a whole. It has two parts: the numerator (the top number) and the denominator (the bottom number). For example, in the fraction ¾, the 3 is the numerator, and the 4 is the denominator.

Why is Learning Fractions Important?

Understanding fractions is important because they are used in daily life, such as cooking and measuring. Also, fractions are the building blocks for more complex math concepts.

Adding Fractions

When Denominators Are the Same

If the fractions have the same denominator, just add the numerators and keep the denominator the same. For example:

• Example: ¾ + ¼ = 7/4 (3 + 1 = 4, denominator stays 4)

When Denominators Are Different

To add fractions with different denominators, follow these steps:

• Step 1: Find the least common multiple (LCM) of the denominators.
• Step 2: Change each fraction to an equivalent fraction with the common denominator.
• Step 3: Add the numerators and write the result over the common denominator.
• Example: ½ + ⅓: The common denominator is 6. Convert to 3/6 + 2/6 = 5/6.

Subtracting Fractions

When Denominators Are the Same

Just like with addition, if the fractions have the same denominator, subtract the numerators:

• Example: 5/6 - 1/6 = 4/6 = 2/3

When Denominators Are Different

Use the same steps as for addition to subtract fractions with different denominators:

• Example: ¾ - ⅖: The common denominator is 20. Convert to 15/20 - 8/20 = 7/20.

Helpful Tips for Success

Here are some strategies to help learners master fractions:

• Utilize visual aids like pie charts or fraction strips to represent fractions.
• Practice with real-life situations, such as sharing pizza or sweets.
• Encourage explaining their problem-solving process.
