Step-by-step solution for: Fractions Decimals and Percents Worksheets - Math Monks
Sure! Let’s solve the table by converting between Fractions, Decimals, and Percents. The key conversions to remember are:
- Fraction → Decimal: Divide numerator by denominator.
- Decimal → Percent: Multiply by 100 (and add % sign).
- Percent → Decimal: Divide by 100.
- Decimal → Fraction: Write as fraction over power of 10, then simplify.
- Percent → Fraction: Write as fraction over 100, then simplify.

- Fraction:
0.22 = 22/100 = 11/50 (simplified)
- Percent:
0.22 × 100 = 22%
✔ Answer: Fraction = 11/50, Percent = 22%
---
- Decimal:
8 ÷ 17 ≈ 0.4706 (rounded to 4 decimal places)
- Percent:
0.4706 × 100 ≈ 47.06%
✔ Answer: Decimal ≈ 0.4706, Percent ≈ 47.06%
*(Note: Since this is a repeating decimal, we round for practical purposes.)*
---
- Decimal:
15 ÷ 17 ≈ 0.8824
- Percent:
0.8824 × 100 ≈ 88.24%
✔ Answer: Decimal ≈ 0.8824, Percent ≈ 88.24%
---
- Fraction:
0.39 = 39/100 → already simplified → 39/100
- Percent:
0.39 × 100 = 39%
✔ Answer: Fraction = 39/100, Percent = 39%
---
- Decimal:
98.9 ÷ 100 = 0.989
- Fraction:
0.989 = 989/1000 → check if reducible?
GCD(989,1000) = 1 → so 989/1000
✔ Answer: Decimal = 0.989, Fraction = 989/1000
---
- Fraction:
0.81 = 81/100 → already simplified → 81/100
- Percent:
0.81 × 100 = 81%
✔ Answer: Fraction = 81/100, Percent = 81%
---
First, convert mixed number to improper fraction or decimal:
30 1/5 % = 30.2%
- Decimal:
30.2 ÷ 100 = 0.302
- Fraction:
0.302 = 302/1000 = 151/500 (divide numerator & denominator by 2)
✔ Answer: Decimal = 0.302, Fraction = 151/500
---
- Decimal:
3 ÷ 11 ≈ 0.2727... → often written as 0.27̅ (repeating), but for table, use 0.2727 (rounded)
- Percent:
0.2727 × 100 ≈ 27.27%
✔ Answer: Decimal ≈ 0.2727, Percent ≈ 27.27%
---
- Fraction:
0.293 = 293/1000 → check simplification: GCD(293,1000)=1 → 293/1000
- Percent:
0.293 × 100 = 29.3%
✔ Answer: Fraction = 293/1000, Percent = 29.3%
---
- Decimal:
38.9 ÷ 100 = 0.389
- Fraction:
0.389 = 389/1000 → GCD(389,1000)=1 → 389/1000
✔ Answer: Decimal = 0.389, Fraction = 389/1000
---
- Decimal:
6 ÷ 7 ≈ 0.8571
- Percent:
0.8571 × 100 ≈ 85.71%
✔ Answer: Decimal ≈ 0.8571, Percent ≈ 85.71%
---
- Fraction:
0.123 = 123/1000 → GCD(123,1000)=1 → 123/1000
- Percent:
0.123 × 100 = 12.3%
✔ Answer: Fraction = 123/1000, Percent = 12.3%
---
- Decimal:
0.08 ÷ 100 = 0.0008
- Fraction:
0.0008 = 8/10000 = 1/1250 (divided numerator & denominator by 8)
✔ Answer: Decimal = 0.0008, Fraction = 1/1250
---
- Fraction:
0.008 = 8/1000 = 1/125 (simplified)
- Percent:
0.008 × 100 = 0.8%
✔ Answer: Fraction = 1/125, Percent = 0.8%
---

📌 Note on Rounding: For repeating decimals like 8/17, 3/11, etc., I used 4 decimal places for practicality. In some contexts, you might write them with a bar (e.g., 0.27̅ for 3/11), but for worksheets, rounding is acceptable.
