Question

12 dogs decreased by 25%

Answer 1

12 x 25/100 =12 x 1/4

25% x 12 = 3

12 - 3 = 9

Answer 2

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

Step-by-step 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* (25)/(100) =12* (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.
