Key Concepts & Vocabulary

TermDefinitionExample Improper FractionA fraction where the numerator (top number) is greater than or equal to the denominator (bottom number). It represents a value of one or more whole units.$ rac{7}{4}$ (seven-fourths) means you have 7 parts, and each whole is divided into 4 parts. This is more than one whole. Mixed NumberA number consisting of a whole number and a proper fraction combined. It represents a value greater than one.$1 rac{3}{4}$ (one and three-fourths) means you have 1 whole unit and $ rac{3}{4}$ of another unit. NumeratorThe top number in a fraction, which tells you how many parts of the whole you have.In $ rac{7}{4}$, the numerator is 7. DenominatorThe bottom number in a fraction, which tells you how many equal parts the whole is divided into.In $ rac{7}{4}$, the denomi...

Core Formulas

Converting Improper Fractions to Mixed Numbers $ \frac{\text{Numerator}}{\text{Denominator}} = \text{Quotient} \frac{\text{Remainder}}{\text{Denominator}} $ To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient becomes the whole number part, the remainder becomes the new numerator, and the denominator stays the same. Converting Mixed Numbers to Improper Fractions $ \text{Whole Number} \frac{\text{Numerator}}{\text{Denominator}} = \frac{(\text{Whole Number} \times \text{Denominator}) + \text{Numerator}}{\text{Denominator}} $ To convert a mixed number to an improper fraction, multiply the whole number by the denominator, then add the original numerator. This sum becomes the new numerator, and the denominator remains the same....
