Question

In a zoo, the ratio of adults to children is 8 to 3. If there are 154 people in the zoo, how may children are there?

Answer 1

The children in the zoo are 42.

Explanation:

Given:

In a zoo, the ratio of adults to children is 8 to 3.

There are 154 people in the zoo.

Now, to find the children there in the zoo.

Let the adults be
`8x`.

And the children be
`3x`.

Total number of people = 154.

According to question:

Adults + children = total number of people.

⇒
`8x+3x=154`

⇒
`11x=154`

Dividing both sides by 11 we get:

⇒
`x=14.`

Thus putting the value of
`x` we get:

Adults = 8 × 14 = 112.

Children = 3 × 14 = 42.

Therefore, the children in the zoo are 42.
