Lessons in this module
Understanding One Percent
Understand what one percent means and use it as the building block for calculating any percentage of a money amount.
Finding Ten Percent Quickly
Use the divide-by-ten shortcut to find 10% of any money amount quickly and accurately without a calculator.
Simple Percentage Discounts
A discount is applied by taking the percentage off the original price — either subtract the discount amount, or multiply by (100 − discount)%. The result is the actual price paid, which is what matters when comparing offers.
Percentage Increase in Prices
A percentage increase is found with ((New − Old) ÷ Old) × 100. Expressing a price rise as a percentage — rather than just a money amount — shows whether the increase is small or significant relative to the original.
Comparing Two Percentage Offers
Two offers can only be compared once both are converted to the same basis — usually price per unit. The headline that looks like the bigger discount is not always the one that actually saves more.
