TermDefinitionExample Percent"Per cent" means "per one hundred" or "out of one hundred." It's a way to express a part of a whole.If you score 80% on a test with 100 questions, you answered 80 questions correctly. Multistep ProblemA problem that requires two or more mathematical operations or steps to find the solution.Finding the price of a shirt after a discount, then adding sales tax. DecimalA number that uses a decimal point to show parts of a whole, often used when calculating with percents.25% can be written as the decimal 0.25. FractionA way to represent a part of a whole, where the top number (numerator) is the part and the bottom number (denominator) is the whole. Percents can be written as fractions with a denominator of 100.50% can be written a...

Converting a Percent to a Decimal P\% = P/100 To use a percent in calculations, divide it by 100 (or move the decimal point two places to the left). Use this rule when you need to multiply a percent by a number. For example, to find 25% of 80, you would convert 25% to 0.25 and then multiply `0.25 \times 80`. Finding a Percent of a Number Part = (Percent/100) \times Whole \quad \text{or} \quad Part = DecimalPercent \times Whole This rule helps you calculate the actual amount that a percentage represents. For instance, to find 15% of $60, you calculate `(15/100) \times 60 = 0.15 \times 60 = 9`. Calculating a New Amount After a Percent Change New Amount = Original Amount \pm (DecimalPercent \times Original Amount) Use '+' for increases (like tax) and '-&#...
