6 3/14•4 5/9-6 3/14 •1 5/9+2 11/14 •3 Решите удобным способом

Answer 1

6 3/14 * 4 5/9 - 6 3/14 * 1 5/9 + 2 11/14 * 3 = 6 3/14 * (4 5/9 - 1 5/9) + 2 11/14 * 3 = 6 3/14 * 3 + 2 11/14 * 3 = 3 * (6 3/14 + 2 11/14) = 3 * 8 14/14 = 3 * 9 = 27

Answer 2

6 3/14 * 4 5/9 - 6 3/14 * 1 5/9 + 2 11/14 * 3 = 6 3/14 * (4 5/9 - 1 5/9) + 2 11/14 * 3 = 6 3/14 * 3 + 2 11/14 * 3 = 3 * (6 3/14 + 2 11/14) = 3 * ((6+2) + (3/14+11/14)) = 3 * (8 + 1) = 3 * 9 = 27

Answer 3

Я могу помочь вам решить эту задачу. Вот подробное решение:

6 3/14•4 5/9-6 3/14•1 5/9+2 11/14•3 = (6+3/14)•(4+5/9)-(6+3/14)•(1+5/9)+(2+11/14)•3 = (87/14)•(41/9)-(87/14)•(14/9)+(39/14)•3 = (3567/126)-(1092/126)+(117/14) = (2475/126)+(117/14) = (2475/126)+(63/42) = (7425/378)+(189/378) = (7614/378) = 20 74/378 = 20 37/189

Ответ: 20 37/189
