Question

In a pet shop 4/9of the dogs are brown,2/9 are white,and the rest are black.what fraction of the dogs are black?

Answer 1

Answer:

3/9

Step-by-step explanation:

Number of brown dogs = 4/9

Number of white dogs = 2/9

Let the rest number of black dogs be considered as x/9.

Therefore,

The total number of dogs in the pet shop =

=> 4/9 + 2/9 + x/9 = 1

=> 6/9 + x/9 = 1

=>( 6 + x)/9 = 1

=> 6 + x = 9

=> x = 9 - 6

=> x = 3

Hence the required fraction of black dogs is 3/9.
