- Convert simple fractions to decimals and vice versa.
- **Percentages (7 mins)**
- Define percentages and relate them to fractions and decimals.
- Show common percentages and their fraction/decimal equivalents (e.g., 50% = 1/2 = 0.5).
- Simple problems converting between percentages, fractions, and decimals.
**3. Guided Practice (10 Minutes)**
- **Fraction, Decimal, Percentage Conversion Practice**
- Hand out worksheets with problems on converting fractions to decimals, decimals to percentages, and vice versa.
