A direct part of a total is requested: x% of N.
Convert the percentage into a multiplier and apply it to the base quantity.
Use fraction equivalents where possible: 12.5%=1/8, 16.67%≈1/6, 25%=1/4, 33.33%≈1/3, 37.5%=3/8, 62.5%=5/8.
Convert awkward percentages into fractions first, then multiply instead of using decimals.
