Divide Unit Fractions by Whole Numbers

Learn how to share fractions fairly!

Understanding Fraction Division

Dividing fractions might sound tricky, but it's just like sharing pizza slices!
When we divide a unit fraction (like ½ or ¼) by a whole number, we're splitting that fraction into equal parts. Imagine you have half a pizza and want to share it with 2 friends. Each person would get ¼ of the whole pizza!

How to Divide Unit Fractions by Whole Numbers

1️⃣ Keep the numerator (top number) the same

2️⃣ Multiply the denominator (bottom number) by the whole number

3️⃣ Simplify your answer if needed

Let's Practice with Examples!

Example 1: Sharing a Chocolate Bar

You have ½ of a chocolate bar and want to share it equally with 3 friends. How much does each person get?

÷ 3 =

We keep the numerator 1 the same, and multiply the denominator by 3:

½ ÷ 3 = 1/(2×3) = ⅙

Each person gets of the chocolate bar!

Example 2: Dividing Juice Equally

You have ¼ liter of juice to pour equally into 2 glasses. How much juice goes in each glass?

÷ 2 =

We keep the numerator 1 the same, and multiply the denominator by 2:

¼ ÷ 2 = 1/(4×2) = ⅛

Each glass gets liter of juice!

Parent Tips 🌟

  • Use real-life examples: Practice with measuring cups in the kitchen or by dividing snacks to make the concept tangible.
  • Visual aids help: Draw circles divided into fractions and physically show how dividing works by coloring sections.
  • Connect to multiplication: Help your child see that dividing by 2 is the same as multiplying by ½ to build number sense.
