Final answer:
To find the ratio of athletes to volunteers at the Olympic games, divide the number of athletes (3,600) by the number of volunteers (20,000), resulting in a ratio of 0.18 or 9/50 when expressed as a fraction.
Step-by-step explanation:
The question is seeking to determine the ratio of the number of athletes to the number of volunteers at the Olympic games. There were a total of 3,600 athletes and 20,000 volunteers. To find the ratio, we divide the number of athletes by the number of volunteers.
Ratio of athletes to volunteers = Number of athletes / Number of volunteers
Ratio of athletes to volunteers = 3,600 / 20,000
Ratio of athletes to volunteers = 0.18
This ratio can also be expressed in its simplest form by dividing both numbers by their greatest common divisor. However, in this case, the ratio is already in its simplest decimal form. If we want to express it as a fraction, it can be simplified to 18/100 or 9/50.
