Question

Найдите значение вырожения 18-10 5/6*1 13/35+6 5/14.

Answer 1

.........=9 1/2

1) 10 5/6*1 13/35=65/6 * 48/35=13*8 /7=104/7=14 6/7
2) 18-14 6/7=3 1/7
3) 3 1/7+6 5/14=3 2/14 +6 5/14=9 7/14=9 1/2

Answer 2

10 5/6 * 1 13/35 = 65/6 * 48/35 = 13*8/7 = 104/7

18 - 14 6/7 = 22/7 = 3 1/7

3 1/7 + 6 5/14 = 133/14 = 9 1/2
