How do you find the percentage of a whole number?
for example:
4 of the 18 cats in a shelter are black.
how do you find the percentage?

Put it in a decimal form. i think it would be like 20% or around that area.

1 find your whole value and the number you want 2 turn into a %                         2 turn the two numbers into a fraction                                                                   3 place the # you want to turn into a percentage over the whole value                 4 convert the fraction into a decimal                                                                     5 multiply the decimal  by 100 to get the %
