(6 1/3 *0,(5) + 0,(4) : 3/19) * 4 5/19

Answer 1

Ответ:

27

Пошаговое объяснение:

0,(5) = (5-0)/9 = 5/9

0,(4) = (4-0)/9 = 4/9

1) 6 1/3 * 0,(5) = 6 1/3 * 5/9 = 19/3 * 5/9 = 95/27 = 3 14/27

2) 0,(4) : 3/19 = 4/9 * 19/3 = 76/27 = 2 22/27

3) 3 14/27 + 2 22/27 = 5 36/27 = 5 4/3 = 6 1/3

4) 6 1/3 * 4 5/19 = 19/3 * 81/19 = 1/1 * 27/1 = 27/1 = 27
