Usually, you CAN'T turn a fraction into a whole number.
You can ONLY do it when the top number is a multiple
of the bottom number. Otherwise, it's not possible.
IF the top number is a multiple of the bottom number,
then take the bottom number, and divide both the top
and the bottom of the fraction by it. Then the top number
will be the whole number that's equal to the original fraction.
Examples:
12 / 5 . 12 is not a multiple of 5 , so there is
NO whole number that's equal to 12/5 .
5 / 12 . Same thing. 5 is not a multiple of 12 .
12 / 3 . 12 is a multiple of 3 .
Divide top and bottom by 3 .
Then you have 4 / 1 .
4 is the same as 12/3 .
