Ok so here it is natural numbers: counting numbers like 1,2,3,4,5... whole numbers: counting numbesr and 0, so 0,1,2,3,4 integers: negative counting numbers and 0, so -3,-2,-1,0,1,2,3... ratioal numbers, things that can be represented in a/b
percent means parts out of 100 so x%=x/100 that is a ratioal number
