I can't imagine. All you have to do is pick any old number, divide the
top and bottom of the fraction by it, and you'll have a new fraction that's
equivalent to 50/100 . And if the number you pick is 2, 5, 10, or 25,
then the new fraction will even have whole numbers on top and bottom.
You can even pick any old number, multiply the top and bottom of the
fraction by it, and you'll have a new fraction that's equivalent to 50/100 .
Can't imagine what's so hard about that.
