Introduction

This tutorial will guide you through the process of multiplying fractions, specifically tailored for Year 5 students. Understanding how to multiply fractions is a fundamental skill in mathematics that will help in various real-life applications, such as cooking and budgeting.

Step 1: Understand the Basics of Fractions

Before you start multiplying fractions, it's important to review what fractions are and how they work.

• Numerator and Denominator: A fraction is made up of two parts:

  • The numerator (top number) represents how many parts you have.
  • The denominator (bottom number) represents how many parts make up a whole.

• Example: In the fraction 3/4, 3 is the numerator and 4 is the denominator.

Step 2: Multiplying Fractions

Now that you understand the basics, let’s move on to multiplying fractions.

1. Multiply the Numerators: Take the top numbers of the fractions and multiply them together.

   • Example: For 1/2 and 3/4, multiply 1 × 3 = 3.

2. Multiply the Denominators: Take the bottom numbers of the fractions and multiply them together.

   • Example: For 1/2 and 3/4, multiply 2 × 4 = 8.

3. Combine the Results: Place the result of the numerators over the result of the denominators.

   • Example: This gives you 3/8.

Step 3: Simplifying the Result

After multiplying the fractions, check if the resulting fraction can be simplified.

• Finding Common Factors: Look for any common factors in the numerator and denominator.

• Dividing: If possible, divide both the numerator and denominator by their greatest common factor (GCF).

• Example: If you end up with 6/12, both numbers can be divided by 6, resulting in 1/2.

Step 4: Practice with Word Problems

Applying your skills in real-world scenarios will enhance your understanding.

1. Cooking Example: If a recipe requires 2/3 cup of sugar and you want to make half of the recipe, multiply:

   • 1/2 × 2/3 = 2/6 = 1/3 cup of sugar.

2. Budgeting Example: If you have 3/5 of your allowance and spend 2/3 of that, calculate:

   • 3/5 × 2/3 = 6/15 = 2/5 of your total allowance spent.

Conclusion

Multiplying fractions involves straightforward steps: multiply the numerators, multiply the denominators, and then simplify if necessary. Practicing with real-life examples can solidify your understanding and make learning more enjoyable.
