🎯 What You'll Learn

You will learn strategies for dividing larger numbers, like amounts over ₦50.

🏪 Market Story

Emeka has ₦60 to share among 4 friends. How much does each get? He thinks: "I know 4 × 15 = 60, so ₦60 ÷ 4 = ₦15." But how did he figure out 4 × 15 = 60? Let's learn a method.

📝 Let's Learn

Strategy: Partition and divide each part.

₦60 ÷ 4: Split 60 into 40 + 20. Then: 40 ÷ 4 = 10 and 20 ÷ 4 = 5. Total: 10 + 5 = ₦15.

Example 1: 72 ÷ 3. Split 72 = 60 + 12. 60 ÷ 3 = 20. 12 ÷ 3 = 4. Total: 24.

Example 2: 85 ÷ 5. Split 85 = 50 + 35. 50 ÷ 5 = 10. 35 ÷ 5 = 7. Total: 17.

Example 3: ₦96 ÷ 4. Split 96 = 80 + 16. 80 ÷ 4 = 20. 16 ÷ 4 = 4. Total: ₦24.

Tip: Choose parts that are easy to divide. Pick multiples of the divisor!

1. 84 ÷ 4: 80 ÷ 4 = 20, 4 ÷ 4 = 1. Total: 21.
2. ₦75 ÷ 3: 60 ÷ 3 = 20, 15 ÷ 3 = 5. Total: ₦25.
3. ₦90 ÷ 5: 50 ÷ 5 = 10, 40 ÷ 5 = 8. Total: ₦18 per day.

💡 Remember

To divide bigger numbers, split them into parts that are easy to divide. Divide each part separately, then add the results. This makes hard division manageable!
