This document defines key terms related to fractions and provides steps for writing a fraction in simplest form. It defines equivalent fractions as fractions that represent the same value, and a fractional equivalent of one as a fraction where the numerator and denominator are the same and equals one whole. It provides the steps to write a fraction in simplest form as finding the greatest common factor (GCF) of the numerator and denominator and dividing both by the GCF. An example demonstrates writing the fraction 3/12 in simplest form as 1/4 by dividing the numerator and denominator by the GCF of 3.

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!
