How to tell if fractions are equivalent 1) Simplify all fractions. If they “reduce” to be the same fraction, then the fractions are equivalent. 2) Cross multiply. We do this by making a “heart” shape. If the two products are equal, then the fractions are equivalent. 3) Get a common denominator and compare numerators. Example: Find out if the fractions 6 10 and are equivalent. 15 50 Way #1: Simplify both fractions completely: 6 2 • 3/ 2 = = 15 5 • 3/ 5 Reduce to different numbers: 10 2 • 5/ 2/ • 1 1 = = = Not Equivalent! 50 10 • 5/ 2/ • 5 5 Way #2: Cross multiply: 6 10 ? 15 50 50 • 6 10 • 15 300 150 Different product: Not Equivalent! Way #3: Get a common denominator between both fractions: Numerators are different: Not Equivalent! 6 10 60 • = 15 10 150 10 3 30 • = 50 3 150
