Start with something useful.
Percent change: choose the base
Percent change = (new - original) ÷ original × 100. The denominator is the original amount, not the final amount.
Example: $48 to $60 is a 25% increase: 12 ÷ 48 × 100. $60 to $48 is a 20% decrease; the base changed.
Convert by cancelling units
1 L = 1,000 mL; 1 kg = 1,000 g; 1 m = 100 cm. Smaller units require a larger number for the same amount.
Example: 0.72 L × (1,000 mL ÷ 1 L) = 720 mL. The L units cancel; dividing by 1,000 would move the wrong way.
