Answer 3

It seems like you are trying to perform some arithmetic operations with different units. Let's break it down step by step:

1. 2 дес. + 8 дес. (десятки) = 20 + 80 = 100 (десятки)

In this step, you're adding 2 tens to 8 tens, resulting in 10 tens or 100.

2. 2 дм. + 8 дм. (дециметры) = 2 + 8 = 10 (дециметры)

In this step, you're adding 2 decimeters to 8 decimeters, resulting in 10 decimeters.

So, the final answers are:

2 дес. + 8 дес. = 100 (десятки) 2 дм. + 8 дм. = 10 (дециметры)
