---

2. What time is it?
Answer: Half past 8 (or “30 past 8”)
*Explanation:* The clock shows the hour hand halfway between 8 and 9, and the minute hand pointing at 6 (which means 30 minutes). So it’s half past 8.

---

---

9. Share 10 between 5:
Answer: 2
*Explanation:* Sharing 10 equally among 5 groups means 10 ÷ 5 = 2 per group. The dice show 5 dots each — total 10 dots — so each die represents one group with 2 dots? Wait — actually, the image shows two dice, each with 5 dots. But the question says “Share 10 between 5” — meaning divide 10 into 5 equal parts. So answer is 2. (The dice may be a visual aid showing 5+5=10, but the division is still 10 ÷ 5 = 2.)

---

10. 2 × 7 =
Answer: 14
*Explanation:* Multiplication: 2 times 7 equals 14.

---
