Asked by Alex L.

About 9 out of 10 adults think it is a good idea to exercise regularly. But the ones who think it is a good idea, only 1 in 6 actually exercises at least 3 times a week. At this rate, how many of the 300 employees in our company exercise regularly?

What I did so far was write this:

9/10 = x/300
x=270

That's a good start.

1/6 = x/270

The answer depends upon how one defines "regularly". If they mean "at least three times a week", the answer is
(9/10)*(1/6)*300 = 45
Answered by Damon
(1/6)(9/10)(300)
= 45

not really a proportion problem

How do I state this question?
Is it..
- At least 45 employees exercise regularly out of that rate

About 45 employees in the company exercise regularly
Answered by Alex L.
It's because of the different rates that confuse me.
Answered by Damon
well, 9/10 of the 300 want to do it
and (1/6) of that (9/10) actually do it
so 1/6 * 9/10 * 300
