Question

-1 2\3 - 2 1\3, 1 1\5*(-5\12), -3 1\9:(-1 1\6)

Answer 1

Ответ:

Пошаговое объяснение:

-1 2\3 - 2 1\3 = -(1 2/3 + 2 1/3) = -3 3/3 = -4 ;

1 1\5*(-5\12) =  6/5 * ( -5/12) = -1/2 ;

-3 1\9:(-1 1\6) = -28/9 : (-7/6) = 28/9 * 6/7 = 8/3 = 2 2/3 ;

Answer 2

-1 + 2\3 = -1 + 0.6667 = -0.3333 -2 + 1\3 = -2 + 0.3333 = -1.6667 1 + 1\5 = 1 + 0.2 = 1.2

Now let's solve the multiplication and division:

1.2 * (-5\12) = 1.2 * (-0.4167) = -0.5

-3 + 1\9 = -3 + 0.1111 = -2.8889 -1 + 1\6 = -1 + 0.1667 = -0.8333

Now let's perform the division:

-2.8889 : -0.8333 = 3.4667

Now let's add all the results together:

-0.3333 - 1.6667 + (-0.5) + 3.4667 = 1.9667

So the final answer is 1.9667.
