Найдем 75% или 3/4:
1) от 96:
3/4 * 96 = 3/4 * (24 * 4) = 3 * 24 = 72.
2) от 400:
3/4 * 400 = 3/4 * (4 * 100) = 3 * 100 = 300.
3) от 782:
3/4 * (391 * 2) = 3 * 391 / 2 = 1173 / 2 = 586,5.
4) от 321:
3/4 * 321 = 3 * 321 / 4 = 963 / 4 = 240,75.
5) от 5000:
5000 - 100%;
x - 75%.
x = 5000 * 75 / 100 = 50 * 75 = 3750.
ответ: 72; 300; 586,5; 240,75; 3750.
