## 📊 PART 1: Complete the Table
We are given a table with some values filled in, and we need to fill in the missing ones using conversions.
Remember:
- To convert decimal → fraction: Write decimal over 100 (if 2 decimal places), then simplify.
- To convert decimal → percentage: Multiply by 100%.
- To convert fraction → decimal: Divide numerator by denominator.
- To convert fraction → percentage: Multiply fraction by 100%.
- To convert percentage → decimal: Divide by 100.
- To convert percentage → fraction: Write as /100, then simplify.
---
- Fraction: 0.05 = 5/100 = 1/20 (simplified)
- Percentage: 0.05 × 100% = 5%
✔ So:
Fraction = 1/20, Percentage = 5%
---
- Fraction: 0.32 = 32/100 = 8/25 (simplified)
- Percentage: 0.32 × 100% = 32%
✔ So:
Fraction = 8/25, Percentage = 32%
---
- Decimal: 23 ÷ 100 = 0.23
- Percentage: (23/100) × 100% = 23%
✔ So:
Decimal = 0.23, Percentage = 23%
---
- Decimal: 7 ÷ 100 = 0.07
- Percentage: (7/100) × 100% = 7%
✔ So:
Decimal = 0.07, Percentage = 7%
---
- Decimal: 41 ÷ 100 = 0.41
- Fraction: 41/100 (already simplified)
✔ So:
Decimal = 0.41, Fraction = 41/100
---
- Decimal: 8 ÷ 100 = 0.08
- Fraction: 8/100 = 2/25 (simplified)
✔ So:
Decimal = 0.08, Fraction = 2/25
---
| Decimal | Fraction | Percentage |
|---------|----------|------------|
| 0.05 | 1/20 | 5% |
| 0.32 | 8/25 | 32% |
| 0.23 | 23/100 | 23% |
| 0.07 | 7/100 | 7% |
| 0.41 | 41/100 | 41% |
| 0.08 | 2/25 | 8% |
---
## 🧮 PART 2: Rewrite each set of 3 in order, starting with the smallest
We need to convert all to the same form (e.g., decimals) to compare easily.
---
Convert all to decimals:
- 7/100 = 0.07
- 12% = 0.12
- 0.09 = 0.09
Order from smallest to largest:
0.07 < 0.09 < 0.12
So:
✔ 7/100, 0.09, 12%
---
Convert to decimals:
- 23/100 = 0.23
- 3% = 0.03
- 0.3 = 0.30
Order:
0.03 < 0.23 < 0.30
So:
✔ 3%, 23/100, 0.3
---
Convert to decimals:
- 9/100 = 0.09
- 10% = 0.10
- 0.01 = 0.01
Order:
0.01 < 0.09 < 0.10
So:
✔ 0.01, 9/100, 10%
---
## ⚖️ PART 3: Put in correct sign (<, >, or =)
Again, convert everything to decimals for easy comparison.
---
70% = 0.70
0.77 > 0.70 → >
✔ 0.77 > 70%
---
30% = 0.30
3/100 = 0.03
0.30 > 0.03 → >
✔ 30% > 3/100
---
42/100 = 0.42
0.42 > 0.3 → >
✔ 42/100 > 0.3
---
7% = 0.07
0.62 > 0.07 → >
✔ 0.62 > 7%
---
29% = 0.29
35/100 = 0.35
0.29 < 0.35 → <
✔ 29% < 35/100
---
35/100 = 0.35
0.35 < 0.4 → <
✔ 35/100 < 0.4
---
## ✔ FINAL ANSWERS:
