Answer 2

Hmmm... I just so happened to learn about this today at school. Too bad I didn't listen. But, if I remember correctly, which I probably didn't, we divided a big number by a small number and multiplied by 100% to get another number or somthing or rather. Try finding a large enough chart if you just need the answer. Heres a link to a small one.
