Q
How many 2/3's are in 2?
A
There are 3 two-thirds (2/3's) in 2, because 2 ÷ (2/3) = 3.
Detailed Explanation:
The Calculation: To find how many 2/3's fit into 2, we divide:
- 2 ÷ (2/3) = ?
Division by Fraction Method: When dividing by a fraction, multiply by its reciprocal:
- 2 ÷ (2/3) = 2 × (3/2)
- = 2 × 3/2
- = 6/2
- = 3
Visual Understanding: Imagine 2 whole pizzas:
- Each pizza is divided into 3 equal slices
- Each 2/3 portion uses 2 slices
- First 2/3: uses 2 slices from pizza 1
- Second 2/3: uses the remaining 1 slice from pizza 1 plus 1 slice from pizza 2
- Third 2/3: uses the remaining 2 slices from pizza 2
- Total: three 2/3 portions
Verification:
- If there are three 2/3's in 2:
- 2/3 + 2/3 + 2/3 = 6/3 = 2 ✓
Alternative Method:
- 2 = 6/3 (convert 2 to thirds)
- How many 2/3's fit in 6/3?
- 6 ÷ 2 = 3 groups
Real-World Application:
- "I have 2 cups of flour. How many 2/3-cup servings?" = 3 servings
- "I have 2 hours. How many 2/3-hour sessions?" = 3 sessions
Important Notes:
- There are 3 two-thirds in 2
- Calculate by: 2 ÷ (2/3) = 3
- Or: 2/3 + 2/3 + 2/3 = 2
