Answer 2

8.68×0.3-2.2=2.604-2.2=0.404

Answer 3

To solve the expression, let's first clarify what the notation means:

(6,6 : 1,2 + 3,18) represents a coordinate pair (x, y) where x = 6 and y = 6.

Next, let's perform the operations step by step:

Step 1: Add the two coordinate pairs (1,2) and (3,18): (1,2) + (3,18) = (1+3, 2+18) = (4, 20)

Step 2: Divide the original coordinate pair (6,6) by the result obtained in Step 1: (6,6 : (4,20)) = (6/4, 6/20) = (1.5, 0.3)

Step 3: Multiply the resulting coordinate pair from Step 2 by 0.3: (1.5, 0.3) x 0.3 = (1.5 * 0.3, 0.3 * 0.3) = (0.45, 0.09)

Step 4: Subtract (2,2) from the result obtained in Step 3: (0.45, 0.09) - (2,2) = (0.45 - 2, 0.09 - 2) = (-1.55, -1.91)

Therefore, the final result of the expression is (-1.55, -1.91).
