Why cant i find what is equivelent to 50/100

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.
