Question

The ratio of taxis to buses to bikes

is 12:5:18.
How many buses are there if there
are 72 bikes?

Answer 1

20 buses

Explanation:

Using the given ratio, we can see that for every 12 taxis, there are 5 buses and 18 bikes.

To get from 18 bikes to 72 bikes, we multiply by 4. Therefore, to figure out the number of buses, we multiply it by 4.

5 * 4 = 20
