📒 The 1-minute cheat sheet
📌 Convert
- Fraction → decimal: divide top ÷ bottom
- Decimal → percent: move point 2 right (×100)
- Percent → decimal: move point 2 left (÷100)
- 0.6 = 6/10 = 3/5 = 60%
✅ Add / Subtract Fractions
- Find a common denominator first
- 3/4 + 1/8 = 6/8 + 1/8 = 7/8
- Simplify by dividing by the GCF
📌 Percent
- part ÷ whole × 100 = percent
- % OF a number: change % to a decimal, then multiply
- 25% of 80 = 0.25 × 80 = 20
