Equivalent Fractions: 2 fractions that
represent the same quantity
ex. 3/6 = 4/8 (both = ½)
• Write equivalent fractions by
multiplying or dividing BOTH the
numerator and denominator by the
same number
ex.
4 (x 3) = 12
7 (x 3) = 21

Simplest Form
Simplest form: a fraction is in simplest form when the numerator
and denominator have no common factors other than 1 ( GCF is 1)
ex.
4/6 = 2/3 (2/3 is in simplest form)
Write a fraction in simplest form by dividing both the numerator
and denominator by the GCF
ex. 24 (÷ 6)
= 4
30 (÷ 6)

factors of 24: 1, 24, 2, 12, 3, 8, 4, 6
factors of 30: 1, 30, 2, 15, 3, 10, 5, 6
