Answer 4

My suggestion to solve and check for which option is correct is by using this method which I love the best to check percentages out of wholes.

Answer 5

% of (whole) = part

for now you are really solving for the percent and the whole is the total (which I believe the number is already provided).

The part is the category total depending in each school type.

The formula is:
is %
--- =. ----
of 100

Is - the past
of - whole
% is the percent (which in this case would be x)

Answer 6

*is - the part

Answer 7

Can you do one for the first option ? just as an example ?
I understand what you're saying but im not sure how to turn the options int that equations.
If not that's fine, I'm just really confused on this /:

Answer 8

*into *that *I'm

Answer 9

I am always ready to give examples!

Answer 10

Ok in the first option, we see that we have to look over at the action category for high school. So far so good?

Answer 11

So far so good.

Answer 12

Now they present us with the percentage and we want to check if the percentage there is correct is presented. So we leave the percent part of the equation blank since we want to solve for it. The whole will be the total votes there are in the high school voting. The part will be the amount of people who chose action as their favorite in high school.

Our equation should be:
__ (where the % goes) of 75 (the row total) = 40 (people who chose action as their favorite in high school).

You're with me?

Answer 13

I'm with you,
But isn't it is/of = %/100 ?
so wouldn't that just be %/75 = 40/x ?

Answer 14

Sorry, I know I'm a tad confusing /:

Answer 15

No problem, we are getting there right now.

Answer 16

So the equation, as we know, is:
is. %
-- =. ---
of. 100

Remember what I told you here.
is - the part (people who chose action in high school)
of - the row total
% - what we are solving for (which can be replaced by x)

Can you fill the proportion for me here?

Answer 17

40/75 = x/100 ?

Answer 18

Perfect!

Answer 19

Can you solve for x here?

Answer 20

Or do you need help?

Answer 21

40 x 100/75 right ?

Answer 22

i got 53.3 repeating..

Answer 23

Are you saying 40 x 100 and then divide by 75?

Answer 24

Yes that's how you do it. So since you got 53.3... Then you know that A May not be a possible answer.

Answer 25

And by the way 53.33... Is in decimal. The percent would be 5333.33%
