🏪 Market Story

Funke, Bola, and Amina are best friends. They always share treats three ways. Today they have 21 chin-chin pieces. How many does each girl get? 21 ÷ 3 = 7 pieces each. Fair sharing among three!

📝 Let's Learn

Dividing by 3 uses the 3 times table in reverse:

• 3 ÷ 3 = 1
• 6 ÷ 3 = 2
• 9 ÷ 3 = 3
• 12 ÷ 3 = 4
• 15 ÷ 3 = 5
• 18 ÷ 3 = 6
• 21 ÷ 3 = 7
• 24 ÷ 3 = 8
• 27 ÷ 3 = 9
• 30 ÷ 3 = 10

Think: "3 times WHAT equals this number?"

Example 1: 18 ÷ 3. Think: 3 × ? = 18. Answer: 3 × 6 = 18, so 18 ÷ 3 = 6.

Example 2: ₦24 ÷ 3 = ₦8. (3 × 8 = 24.)

Example 3: 27 ÷ 3 = 9. (3 × 9 = 27.)
