Fill in the missing decimals and fractions for each percentage listed in this conversion practice sheet.

To solve the problem, we need to convert each given percentage into its decimal and fractional forms. Let's go through each step systematically.

Conversion Rules:

1. From Percent to Decimal: Divide the percentage by 100.
- Example: \( 40\% = \frac{40}{100} = 0.4 \)

2. From Percent to Fraction: Write the percentage as a fraction over 100, then simplify if possible.
- Example: \( 40\% = \frac{40}{100} = \frac{2}{5} \)

Now, let's fill in the table step by step.

- Decimal: \( \frac{15}{100} = 0.15 \)
- Fraction: \( \frac{15}{100} = \frac{3}{20} \)

#### 6. \( 82\% \)
- Decimal: \( \frac{82}{100} = 0.82 \)
- Fraction: \( \frac{82}{100} = \frac{41}{50} \)

#### 7. \( 95\% \)
- Decimal: \( \frac{95}{100} = 0.95 \)
- Fraction: \( \frac{95}{100} = \frac{19}{20} \)

#### 8. \( 2\% \)
- Decimal: \( \frac{2}{100} = 0.02 \)
- Fraction: \( \frac{2}{100} = \frac{1}{50} \)

#### 9. \( 150\% \)
- Decimal: \( \frac{150}{100} = 1.5 \)
- Fraction: \( \frac{150}{100} = \frac{3}{2} \)

#### 10. \( 300\% \)
- Decimal: \( \frac{300}{100} = 3.0 \)
- Fraction: \( \frac{300}{100} = 3 \) (or \( \frac{3}{1} \))

#### 11. \( 12.5\% \)
- Decimal: \( \frac{12.5}{100} = 0.125 \)
- Fraction: \( \frac{12.5}{100} = \frac{125}{1000} = \frac{1}{8} \)

#### 12. \( 31\% \)
- Decimal: \( \frac{31}{100} = 0.31 \)
- Fraction: \( \frac{31}{100} \) (already in simplest form)

#### 13. \( 48\% \)
- Decimal: \( \frac{48}{100} = 0.48 \)
- Fraction: \( \frac{48}{100} = \frac{12}{25} \)

#### 14. \( 124\% \)
- Decimal: \( \frac{124}{100} = 1.24 \)
- Fraction: \( \frac{124}{100} = \frac{31}{25} \)

#### 15. \( 135\% \)
- Decimal: \( \frac{135}{100} = 1.35 \)
- Fraction: \( \frac{135}{100} = \frac{27}{20} \)

#### 16. \( 37.5\% \)
- Decimal: \( \frac{37.5}{100} = 0.375 \)
- Fraction: \( \frac{37.5}{100} = \frac{375}{1000} = \frac{3}{8} \)

Final Answer:

Here is the completed table:

| PERCENT | DECIMAL | FRACTION |
|---------|---------|----------|
| 40% | 0.4 | \(\frac{4}{10}\) or \(\frac{2}{5}\) |
| 90% | 0.9 | \(\frac{9}{10}\) |
| 55% | 0.55 | \(\frac{11}{20}\) |
| 28% | 0.28 | \(\frac{7}{25}\) |
| 50% | 0.5 | \(\frac{1}{2}\) |
| 15% | 0.15 | \(\frac{3}{20}\) |
| 82% | 0.82 | \(\frac{41}{50}\) |
| 95% | 0.95 | \(\frac{19}{20}\) |
| 2% | 0.02 | \(\frac{1}{50}\) |
| 150% | 1.5 | \(\frac{3}{2}\) |
| 300% | 3.0 | \(3\) or \(\frac{3}{1}\) |
| 12.5% | 0.125 | \(\frac{1}{8}\) |
| 31% | 0.31 | \(\frac{31}{100}\) |
