(4 5/11 + 7 6/11)- 9 8/17 - 5 11/17=

Answer 1

Відповідь:

7 8/13 + 11 5/13 -4 3/17 = 18 (8+5)/13 - 4 3/17 = 18 13/13 - 4 3/17 = 19 - 4 3/17 = 18 17/17 - 4 3/17 = 14 14/17

(4 5/11 + 7 6/11) - 9 8/17 - 5 11/17 = 11 11/11 - 9 8/17 - 5 11/17 = 12 - 9 8/17 - 5 11/17 = 12 - (9 8/17 + 5 11/17) = 12 - 14 19/17 = 12 - 15 2/17 = -3 2/17
