Answer 3

To calculate the expression 11707:23+4687:43-643, it seems that you are using a colon (:) instead of a colon (:) to separate hours and minutes. Assuming that you meant to use a colon (:) as the time separator, I will convert the hours and minutes into a decimal format before performing the arithmetic operations.

11707:23 can be converted to decimal format as follows: 11707 hours + (23/60) hours = 11707.3833 hours

Similarly, 4687:43 can be converted to decimal format as follows: 4687 hours + (43/60) hours = 4687.7167 hours

Now, let's perform the arithmetic operations:

11707.3833 + 4687.7167 - 643 = 14051.1

Therefore, the result of the expression 11707:23+4687:43-643 is approximately 14051.1.
