A percent is a way of a expressing a part out of 100. Remember learning about ratios and how they compare quantities? A part-to-whole ratio is a ratio that compares a part of a whole to another part of a whole. A percent is a part-to-whole ratio where the whole is 100. 40%, or 40 out of 100, is a ratio that compares 40, the part, to 100, the whole.
