Question #f63ce

Answer 1

28

Explanation:

`5 :7` is the ratio between bicycles and buses, not their actual number.

Their actual number will be a multiple of these numbers.

What I mean is that the number will be `5x` bicycles and `7x` buses, where `x` is any whole number.

Then, the total number of vehicles is `5x + 7x = 12x`, which in this case is `48`.

So,
`12x = 48`

Dividing both sides by 12,

`x = 48/12`

Therefore, `x = 4`.

Now, the number of buses is `7x`, `7xx4 = 28`.
