Answer 2

Answer in detail.

Dunya mixed up the plots of all the fairy tales. Seva decided to restore the plots of all the fairy tales. In three days he restored the plots of 27 fairy tales. How many days will it take him to restore the plots of 81 fairy tales, if he restores the same number of fairy tales every day?

This is a math problem that can be solved by using the concept of proportionality. Proportionality means that two quantities are related by a constant ratio or factor. For example, if Seva restores 9 fairy tales in one day, then he restores 18 fairy tales in two days, because 18 is 9 times 2. The ratio of fairy tales to days is 9:1, which is constant.

To solve this problem, we can use a cross-multiplication method, which is a way of finding the missing value in a proportion. We can write the proportion as:

9 fairy tales / 1 day = 81 fairy tales / x days

where x is the unknown number of days. To find x, we can cross-multiply the terms and get:

9x = 81

Then we can divide both sides by 9 and get:

x = 9

Therefore, it will take Seva 9 days to restore the plots of 81 fairy tales, if he restores 9 fairy tales every day.
