Разделите число 196 на части в отношении 3:7:11 1:2:4 1/3:1/4:3 5:7,5:15,5

1) (Число делим на части и умножаем поочередно на каждую из частей)

196 / (3 + 7 + 11) * 3 = 196/21 * 3 = (196 * 3) / 21 = (196 * 1) / 7 = 28,

196 / (3 + 7 + 11) * 7 = 196/21 * 7 = (196 * 7) / 21 = (196 * 1) / 3 = 65 1/3,

196 / (3 + 7 + 11) * 11 = 196/21 * 11 = (196 * 11) / 21 = 2 156/21 = 102 14/21 = 102 2/3;

2) 196 / (1 + 2 + 4) * 1 = 196/7 * 1 = 28,

196 / (1 + 2 + 4) * 2 = 196/7 * 2 = (196 * 2) / 7 = (28 * 2) / 1 = 56,

196 / (1 + 2 + 4) * 4 = 196/7 * 4 = (196 * 4) / 7 = (28 * 4) / 1 = 112;

3) 196 / (1/3 + 1/4 + 3) * 1/3 = 196 / (4/12 + 3/12 + 3) * 1/3 = 196/3 7/12 * 1/3 = 196 : 43/12 * 1/3 = 196 * 12/43 * 1/3 = (196 * 12 * 1) / (43 * 3) = 2 352/129 = 18 30/129;

196 / (1/3 + 1/4 + 3) * 1/4 = 196 / (4/12 + 3/12 + 3) * 1/4 = 196/3 7/12 * 1/4 = 196 : 43/12 * 1/4 = 196 * 12/43 * 1/4 = (196 * 12 * 1) / (43 * 4) = (196 * 3 * 1) / (43 * 1) = 588/43 = 13 29/43;

196 / (1/3 + 1/4 + 3) * 3 = 196 / (4/12 + 3/12 + 3) * 3 = 196/3 7/12 * 3 = 196 : 43/12 * 3 = 196 * 12/43 * 3 = (196 * 12 * 3) / 43 = 7056/43 = 164 4/434

4) 196 / (5 + 7,5 + 15,5) * 5 = 196/28 * 5 = (196 * 5) / 28 = (7 * 5) / 1 = 35,

196 / (5 + 7,5 + 15,5) * 7,5 = 196/28 * 7,5 = (196 * 7,5) / 28 = (7 * 7,5) / 1 = 52,5;

196 / (5 + 7,5 + 15,5) * 15,5 = 196/28 * 15,5 = (196 * 15,5) / 28 = (7 * 15,5) / 1 = 108,5.
