@JV: this is like one of the problems we worked a couple of hours ago.

Answer 3

The one with 90%. So follow that procedure, or the one across is recommending.

Answer 4

@ James, Yeah I know but I still don't understand how to do the problem... :/

Answer 5

Nebi,

:)

I wonder what 66.2 people look like!

Answer 6

Let X be the number of people in the theater originally.

How do write one fifth of X?

Answer 7

20(5)=100

Answer 8

66(5)=?

Answer 9

\[\left(\begin{matrix}1 \\ 5\end{matrix}\right)x\]

Answer 10

?

Answer 11

Do you mean X/5 ?

Answer 12

I'm getting extremely confused

Answer 13

X/5 is one fifth of X. Do agree with that?

Answer 14

If 66 people = 1/5 (one fifth).....then 66 x 5 = 5/5
66 x 5 = 330

Answer 15

sure I guess... Idk what it means but I'm sure your right James

Answer 16

i just typed that

Answer 17

Well, it's true that X/5 means one fifth of X

Now what do we know about one fifth of X, the number of patrons?

It is equal to 66

That is:

X/5 = 66

How do you now solve that equation for X?

Answer 18

I found that it was 330... Sorry to make you upset?......

Answer 19

Why did you delet your comment?

Answer 20

Yes, 330 is right.

Answer 21

Or you can do it in terms of percentages:

66 is 20%. We know this because it tells us that 66 is one fifth of the audience.
So, you do 66 divided by 0.20 (the 20%) = 330

You can check its right by reversing it....330 x 0.2 = 66 !
