A bill of 45 out of a 60 budget is 75 percent. The same formula covers test scores, attendance, progress toward a goal, and how much of a total any single item represents.
People ask two different things: what percent is X of Y (27 out of 40 is 67.5 percent), and what is X percent of Y (27 percent of 40 is 10.8). The first divides, the second multiplies by the rate. A percentage calculator that offers both modes keeps you from applying the wrong one.
