Effective Strategies for Converting 12.25 to a Fraction
- Decimal to Fraction Conversion: Divide the decimal part by 10^n, where n is the number of decimal places. Multiply the numerator and denominator by 10^n.
- Mixed Number to Fraction: Multiply the whole number by the denominator of the fraction and add the numerator. Use this sum as the new numerator over the original denominator.
- Long Division: Divide the decimal part by 1, then by 2, 3, and so on until the remainder is zero or repeats. The divisor at which the remainder first repeats is the denominator. The numerator is the sum of the quotients from each division step.
| Strategy | Example | Result |
|---|---|---|
| Decimal to Fraction | 12.25 ÷ 10^2 = 1225/100 | 1225/100 |
| Mixed Number to Fraction | 12 × 5 + 1 = 61/5 | 61/5 |
| Long Division | 12.25 ÷ 1 = 12 R 0.25 | |
| Long Division (Continued) | 0.25 ÷ 2 = 0.125 | |
| Long Division (Final) | 0.125 ÷ 8 = 0.015625 | |
| 12.25 = 12 + 1/4 = 12 and 1/4 |
Common Mistakes to Avoid
- Confusing Fractions and Decimals: Remember that fractions and decimals are different representations of the same quantity.
- Dividing by Zero: Always ensure that the denominator of a fraction is not zero.
- Improper Simplification: Only simplify fractions when both the numerator and denominator have no common factors greater than 1.
Advanced Features of 12.25 as a Fraction
