TermDefinition
reciprocal any two numbers whose product is 1. Flip a fraction
divide a fraction multiply by its reciprocal (KCF- keep, change, flip)
mixed number a number with a whole number and fraction
improper fraction a fraction where the numerator (top) is larger (or equal) than the denominator (bottom)
dividing mixed numbers change into improper fraction, then multiply by the reciprocal (KCF)
change a mixed number into an improper fraction Numerator (top): multiply the whole number by the denominator and add the numerator Denominator: stays the same
scale up Multiply the numerator and denominator by the same number (to make a common denominator)
multiply fractions Multiply numerators and denominators Cross cancel OR simplify if necessary
simplify a fraction Divide both the top and bottom of the fraction by the Greatest Common Factor. Example: Simplify the fraction 8/12 : 1. The largest number that goes exactly into both 8 and 12 is 4, so the Greatest Common Factor is 4.
cross cancel Simplifying BEFORE you multiply the fractions together. You must do this diagonally, by dividing the numerator and denominator by the same number.
Multiply Mixed Numbers Change them into improper Fractions, then use the rules for Multiplying Fractions
Find the missing side when given the area and one side Divide the area by the given side Ex. Area = 50, Length = 5 What is the width? 50/5 = 10
Fraction The number of parts of a whole. A way to represent division.
Numerator The top number, says how many parts we have.

Equivalent Fractions Two or more fractions that have the same value even though they look different.
Simplest Form When the top and bottom of a fraction cannot be any smaller, while still being whole numbers.
Scaling down When you divide the top and bottom of a fraction by the same number to make an equivalent fraction. Also known as reducing or simplifying.
