Let's break down the expression step by step:

1. 24\96 = 1/4
2. 24\48 = 1/2

Now we can substitute these values into the expression:

2*(1/4 - 5) + 3*(1/2 + 3)/2 - (1/2 + 9)/2 : (1/2) * ((1/2 - 1)/2 - (1/2 + 1)*(1/2 - 2) - 7)

Now simplify each part of the expression:

2*(1/4 - 5) = 2*(-19/4) = -38/4 = -19 3*(1/2 + 3)/2 = 3*(7/2)/2 = 21/2 (1/2 + 9)/2 = 19/2 (1/2 - 1)/2 = -1/4 (1/2 + 1)(1/2 - 2) = (3/2)(-3/2) = -9/4

Now substitute these values back into the expression:

-19 + 21/2 - 19/2 : (1/2) * (-1/4 - 9/4 - 7) -19 + 21/2 - 19/2 : (1/2) * (-17/4 - 7) -19 + 21/2 - 19/2 : (1/2) * (-41/4) -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8 -19 + 21/2 - 19/2 : -41/8

Therefore, the final answer is:

-19 + 21/2 - 19/2 - (-41/8) = -38 + 21/2 + 19/2 + 41/8 = -38 + 20.5 + 9.5 + 5.125 = -3.875
