Exchange Rate Tips
- Check the direction: Make sure you're multiplying or dividing correctly
- Commission timing: Some apply commission to original amount, others to converted amount
- Round sensibly: Currency amounts usually round to 2 decimal places
- Compare total cost: Include all fees when comparing exchange services
- Inverse rates: If given EUR/GBP = 0.87, then GBP/EUR = 1 ÷ 0.87 = 1.15
- Multi-step conversions: GBP → USD → JPY requires two exchange rates
- Real-world context: Consider whether rates seem reasonable (£1 ≈ $1.20-1.30)
