ksyushenkа · Answer

(-2 1/6 - 3 1/4):2 3/5 + 2/3*2 1/4 - 5 1/6
-2 1/6- 3 1/4= -2 2/12-3 3/12= -5 5/12
-5 5/12 : 2 3/5 = -65/12: 13/5= -65/12* 5/13= - 25/12= -2 1/12
2/3* 2 1/4= 2/3* 9/4= 3/2= 1 1/2
-2 1/12+ 1 1/2= -2 1/12 + 1 6/12= -1 13/12 + 1 6/12= - 7/12
-7/12 - 5 1/6= -7/12 - 5 2/12= - 5 9/12 = -5 3/4
ответ: -5 3/4
