Answer 2

Solution: The number of dogs left after 25% are decreased, is 9 and number of dogs decreased by 3.

Explanation:

Let the number of dogs after decresing 25%  be x.

It is given that the number of dogs are 12 after that he number of dogs decreased by 25%.

First we have to find 25% f 12.

$12\times \frac{25}{100} =12\times \frac{1}{4}$

$25\% \text{ of }12=3$

Since number of dogs decreased by 25%, therefore subtract 3 from 12.

$12-3=9$

Therefore, the number of dogs left after 25% are decreased, is 9 and number of dogs decreased by 3.
