Answer 3

To solve the given expression, we need to perform addition and subtraction operations with different units of length. Let's break down the expression step by step:

1 meter (1м) + 2 decimeters (2дм): To add these two lengths, we need to convert decimeters to meters. Since 1 decimeter is equal to 0.1 meters, we can rewrite the expression as: 1 meter + (2 decimeters * 0.1) = 1 meter + 0.2 meters = 1.2 meters.

7 meters (7м) + 7 decimeters (7дм): Again, we need to convert decimeters to meters. Since 1 decimeter is equal to 0.1 meters, we can rewrite the expression as: 7 meters + (7 decimeters * 0.1) = 7 meters + 0.7 meters = 7.7 meters.

-56 decimeters (-56дм) + 5 meters (5м): To add these two lengths, we need to convert meters to decimeters. Since 1 meter is equal to 10 decimeters, we can rewrite the expression as: (-56 decimeters) + (5 meters * 10) = -56 decimeters + 50 decimeters = -6 decimeters.

2 meters (2м) + 8 decimeters (8дм): Again, we need to convert decimeters to meters. Since 1 decimeter is equal to 0.1 meters, we can rewrite the expression as: 2 meters + (8 decimeters * 0.1) = 2 meters + 0.8 meters = 2.8 meters.

-15 decimeters (-15дм) + 8 decimeters (8дм): To add these two lengths, we simply add the numbers together: -15 decimeters + 8 decimeters = -7 decimeters.

2 decimeters (2дм) + 5 centimeters (5см
