Lesson 4 5 equivalent fractions
- 1. Name ___________________________________ Date __________________ Mrs. Labuski / Mrs. Rooney Per ___________ Lesson 4-5 Equivalent Fractions VOCABULARY DEFINITION EXAMPLE Fractions that represent Equivalent the same value 1=2=4 Fractions 2 4 8 When the numerator and denominator are 6=1 Fractional the same it equals one 6 Equivalent of whole. Dividing by “one” does One not change the value of the number When the GCF of the numerator and the denominator is one. 18 ÷ 6 = 3 ~~~~~~~~~~~~ Simplest Form Divide by the GCF 24 ÷ 6 = 4 (Fractional equivalent of one) to find the simplest form.
- 2. To write a fraction in simplest form 3 12 1. Find the GCF of the numerator and denominator; 3: 1,3 12:1,2,3,4,6,12 2. Divide the numerator and denominator by the GCF 3÷ 3=1 (fractional equivalent of one) 12÷ 3 4 So 3 written in simplest form is 1 12 4 HINT: If the numerator is one, then the fraction is in simplest form! HINT: See if the numerator IS the GCF!
