We can use different language for making the

This fraction is as simple as we can make it

Equivalent Fractions

Look for numbers that both the NUMERATOR and the

DENOMINATOR can be divided by. We want numbers

bigger than 1.

We call these COMMON FACTORS

Equivalent Fractions

These numbers have 3 as a common factor. This

If the top and bottom number are not DIVISIBLE by

the same number, we stop.
