Answer 2

I can help you with your math question.

To perform the action, you need to add the lengths in the same units. You can convert decimeters (дм) to centimeters (см) by multiplying by 10. For example, 7 дм = 70 см.

Then, you can add the corresponding centimeters together. For example, 70 см + 9 см = 79 см.

Finally, you can simplify the result by converting centimeters back to decimeters if possible. For example, 79 см = 7 дм 9 см.

Therefore, the answer is:

$$7 \text{ дм } 15 \text{ см } + 9 \text{ дм } 27 \text{ см } = 16 \text{ дм } 42 \text{ см }$$
