12 dogs decreased by 25%
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.
