well you can multiply the top and bottom (numerator and denominator) of the fraction by any constant
eg
1/2=2/4=3/6= 100/200 = 400/800 =...

well explain :)
OpenStudy (pokemon23):
The top and bottom of the fraction must always be a whole number.
So, what you divide by must divide evenly (ie no remainders) for both the top and bottom numbers.
You only multiply or divide, never add or subtract, to get an equivalent fraction.

the fraction 3/5 for example is in its simplest fraction form,

so 12 = 3x4
and 15 is 3x5
so 12/15 =3x4/3x5
we can cancel like terms from the numerator and denominator
cancel the 3
12/15= 4/5

o: i see, because there has to be a number for bottom and top to make the same ones
