Let's try one:
Let's reduce
What goes into the numerator AND the
denominator?
3
goes in... So, let's divide it out!
Hey, now it's easy! Do you see that
9 goes in?
so
The best way to do it is to get the
GCF (greatest common factor) of 27 and 108...
| The factors of 27: |
|
1,
3, 9, 27
|
| The factors of 108: |
| 1,
2, 3, 4, 6, 9, 12, 18, 27,
36, 54, 108 |
The GCF is
27.
If we divide by the GCF, we can do
it in one shot:
But, you know what?
If you can't find the GCF, just start
dividing out stuff you see like we did at first.
