Answer 2

Let's break down the given mathematical expressions one by one:

1. 129м 60 см is a length in meters and centimeters. To perform any arithmetic operation with this value, we need to convert it to a single unit. The most common unit for length is meters, so we can convert 60 centimeters to meters by dividing it by 100:

129м 60 см = 129 + 60/100 = 129.6 м

2. 5м 40см is also a length in meters and centimeters. We can convert it to meters in the same way:

5м 40см = 5 + 40/100 = 5.4 м

23ч 21 мин is a duration in hours and minutes. We can perform arithmetic operations directly with this value.

3. To subtract 13ч 48 мин from 23ч 21 мин, we need to convert both durations to a common unit. Let's convert everything to minutes:

23ч 21 мин = 2360 + 21 = 1401 мин 13ч 48 мин = 1360 + 48 = 828 мин

Subtracting 828 from 1401, we get:

1401 - 828 = 573 мин

So the result of the expression is 573 minutes.

4. Let's simplify the expression step by step:

7216:604 = 11.95 11.95 + 2018 = 3029.95 86 * 3029.95 = 260868.7 260868.7 - 181708 = 79160.7

So the result of the expression is 79160.7.

Therefore, the final answer is: 573 - 79160.7 = -78587.7
