20 ÷ 4.

**The reasoning** Division asks: "How many groups of 4 can I make from 20?" Think of it practically: If you have ₦20 and want to share it equally among 4 friends, how much does each person get? 20 ÷ 4 = 20/4 = 5 You can verify: 5 × 4 = 20 ✓ Another way: Keep subtracting 4 from 20 until you reach zero: 20 - 4 = 16 16 - 4 = 12 12 - 4 = 8 8 - 4 = 4 4 - 4 = 0 You subtracted 4 exactly **5 times**. **Why the wrong options tempt you** - **Option A (3):** You might subtract wrongly or confuse this with a harder problem - **Option B (4):** This is the divisor itself—don't mix up what you're dividing *by* with the answer - **Option D (6):** Careless addition (4 + 2) or rushing without proper calculation **Quick takeaway** Division is asking "how many groups?" or "how much per person?"—always verify by multiplying your answer back with the divisor.
