Toasta AI Explanation
Why the answer is C, and why the others tempt you.
**The reasoning** "Half of 80" means dividing 80 into two equal parts. Mathematically, we write this as: 80 ÷ 2 = 40 Or you can think of it as: ½ × 80 = 40 Either way, you're splitting 80 into two groups. If you have ₦80 and share it equally between two people, each person gets ₦40. Simple! **Why the wrong options tempt you** - **A) 20** — This is ¼ of 80 (80 ÷ 4). You might pick this if you rushed and divided by 4 instead of 2. - **B) 30** — This doesn't follow any clean division of 80. Pure distraction. - **D) 50** — This looks "round" and close to 80, so your brain might grab it if you're guessing quickly. But 50 × 2 = 100, not 80! **Quick takeaway** "Half" always means "÷ 2" — if doubling your answer doesn't give you back the original number, it's wrong!
