Step-by-Step Guide
- 1Divide numerator by denominator: 1/4 = 0.25
- 2Repeating decimals: 1/3 = 0.333... use bar notation
- 3Terminating decimals: exact representation
Worked Examples
Input
5/8 fraction
Result
0.625 decimal (exact, terminating)
Powers of 2 denominator = terminating
Common Mistakes to Avoid
- ✕Assuming all fractions have short decimal representations
- ✕Not recognizing repeating pattern (can span many digits)
