Answer 2

To solve the given expressions:

1. 3:0,19 + 1 - 2,8: It appears that you're using a notation that separates the whole number part from the decimal part using a colon (":"). To simplify this expression, let's convert the mixed numbers into decimals:

   3:0 = 3.0 2,8 = 2.8

   Now we can solve the expression: 3.0 + 1 - 2.8 = 4.0 - 2.8 = 1.2

   Therefore, the result of the expression is 1.2.

2. 17:0,25 - 3: Again, let's convert the mixed number to decimals:

   17:0 = 17.0 0,25 = 0.25

   Now we can solve the expression: 17.0 - 0.25 - 3 = 16.75 - 3 = 13.75

   Therefore, the result of the expression is 13.75.
