Convert the percentage to a decimal and multiply the decimal by the price to deduct a percentage from a price. The amount to deduct from the original price is the solution.
To deduct 25% from a $20 price, first convert 25% to a decimal. The decimal form of 25% is.25, which equals 25 out of a total of 100. The decimal is then multiplied by the original price. Twenty divided by.25 equals five. As a result, 25% of the $20 price equals $5. Subtracting 25% from the price is equivalent to deducting $5 from the price. An item that costs $20 with a 25% discount is sold for $15 in this example.
