Answer:
Is there any choices? I'd either say 3/5 or 60/100.
Step-by-step explanation:
The reason being, both would equal around 60% I believe. 60% is 3/5th's of a 100, and 60/100 is simply 60 out of 100. Unless your going farther than I'm not entirely sure. I'm sorry.

Answer:
0.0158 = 1.58% probability that all of them are under 18.
Step-by-step explanation:
Probability of independent events:
If three events, A, B and C are independent, the probability of all happening is the multiplication of the probabilities of each happening, that is:

The percentage of people under the age of 18 was 23.5% in New York City, 25.8% in Chicago, and 26% in Los Angeles.
This means that 
If one person is selected from each city, what is the probability that all of them are under 18?
Since the three people are independent:

0.0158 = 1.58% probability that all of them are under 18.
2(3r+7)−(2+r)
Use distributive property:
6r + 14 - 2 - r
Simplify by combining like terms:
5r +12
