Half of 50.

**The reasoning** "Half of 50" means you're **dividing 50 into two equal parts**. In mathematical terms: ½ × 50 = 50 ÷ 2 = **25** Think of it practically: If you have ₦50 and share it equally between two people, each person gets ₦25. That's what "half" means — one part out of two equal parts. **Why the wrong options tempt you** - **A) 20** — You might rush and think "half sounds like 20-something" without calculating. Or you confused it with "two-fifths" (2/5 × 50 = 20). - **C) 30** — This could trick you if you mistakenly did 50 − 20 instead of 50 ÷ 2. It's a common mental slip. - **D) 50** — Choosing this means you didn't divide at all — you just kept the original number. **Quick takeaway** "Half" always means **divide by 2** — whether it's half of money, marks, or any number; ½ × n = n ÷ 2.
