Q
How many 2s make 12?
A
Six 2s make 12, because 2 + 2 + 2 + 2 + 2 + 2 = 12, or simply 12 ÷ 2 = 6.
Detailed Explanation:
The Calculation:
- Division approach: 12 ÷ 2 = 6
- Multiplication verification: 6 × 2 = 12
- Addition approach: 2 + 2 + 2 + 2 + 2 + 2 = 12
Understanding the Question: This asks: "How many times does 2 fit into 12?" or "What times 2 equals 12?"
Visual Representation: Imagine 12 cookies:
- Arrange them in groups of 2
- You'll have 6 groups
- Therefore, six 2s make 12
Mathematical Relationship:
- If 6 × 2 = 12, then 12 ÷ 2 = 6
- Multiplication and division are inverse operations
Real-World Examples:
- "How many pairs of socks in 12 socks?" = 6 pairs
- "How many $2 bills make $12?" = 6 bills
- "How many 2-minute intervals in 12 minutes?" = 6 intervals
Related Problems:
- How many 3s make 12? → 4 (12 ÷ 3 = 4)
- How many 4s make 12? → 3 (12 ÷ 4 = 3)
- How many 6s make 12? → 2 (12 ÷ 6 = 2)
Important Notes:
- Six 2s make 12
- Solved by division: 12 ÷ 2 = 6
- Verified by multiplication: 6 × 2 = 12
