You change denominators by multiplying the fraction by 1. The name for 1 that you use is the key. 1 has many names: 2/2 3/3 4/4 5/5 6/6 7/7 you get my drift. You choose the name for 1 based on the denominator you want to end up with.

4. Mertsj

If your denominator is 3 and you want to end up with a denominator of 12, then you would choose 4/4 as your name for 1

So long as you multiply the numerator when you multiply the denominator (by the same #) it dosnt matter what you multiply it by

6. Mertsj

$\frac{2}{3}(\frac{4}{4})=\frac{8}{12}$

7. Mertsj

If you wanted to end up with a denominator of 15, you would choose 5/5 as your name for 1

You can also divide, which I fine a lot easier

9. Mertsj

$\frac{2}{3}(\frac{5}{5}) = \frac{10}{15}$
