Lets say, you have a fraction, 1/2. You need to multiply the numerator and denominator by the same number Larger than 1 For example, 1/2. 1x2=2, 2x2=4. SO make it 2/4. That is the exact same thing but looking different, and you can do that to any number and multiply it by any number larger the 1.
Hope this helps :)
