Answer 2

It looks like you've provided an expression with some numbers and a ratio. Let's break down the expression step by step:

1. The expression starts with "1-2," which means you are subtracting 2 from 1, resulting in -1.

2. Next, you have "86:(-1, 1)," which appears to be a ratio or division operation. However, the format is a bit unclear. If you intended to calculate the ratio of 86 to -1 and 1, it would be written as "86/(-1, 1)." In this case, it's not a standard mathematical operation.

3. Finally, you have "+7:5," which again appears to be a ratio. Adding a ratio is not a standard mathematical operation either.

If you could provide more context or clarify the expression, I would be happy to help you with the calculation or explanation.
