How do you calculate percentage?

For example, like the show DEAL or no DEAL. Like he'll say , there's a 66% chance of you winning the money, or, in a survey of a hundred people, 12% said they do not like pies. Please help?How do you calculate percentage?
Ok these people are telling you how to do it the long way. If you made a poll out of 457 people and 345 people said yes to whatever the poll was (345) divided by the total (457) equals .7549 you move the decimal to the right 2 places (thats the same as multiplying it by 100) and you get 75.4 so you round it to 75% :)
Division



Let's say in Deal or No Deal there are 6 cases left:

$1

$100

$750

$25 000

$200 000

$1 000 000



Let's say you wanted to figure out the chance of winning over $100000. Well, since there are 2 cases over $100 000, and there are 6 cases, there is a 2 in 6 chance, or 2/6, of winning over $100 000,



Now, you divide. 2 divided by 6 is 0.3333333333...



Now, you must multiply by 100. 0.3333333... times 100 is 33.33



Therefore, there is a 33.33% chance of winning over $100 000!!How do you calculate percentage?
It's all a matter of division. Lets use deal or no deal for example. If there are 26 cases, and one of them have 1,000,000 in it, then you have a 1 in 26 chance of picking it.



1/26 = 0.038



You then multiply your answer by 100



0.038 X 100 = 3.8



So you have a 3.8% change of picking the 1,000,000 case.




If it's a hundred, it's easy.

Let's pretend 53% of people like cars

53%=0.53 or 53/100

53 people like cars out of 100 people

If it's not a hundred (or 10 or 1000)

you multiply or divide so the number is 100 (or 10 or 1000)

Let's say out of 2 hundred people

Pretend 82% of people hates frogs

82%=0.41 or 82/200 or 41/100 (divide by 2)

you divide 200 to 100, so is the 82%

so out of 100 people, 41% of people hate frogsHow do you calculate percentage?
12% of 100 is 12 ... Why? because you move the decimal over to the left twice and multiply, in this case



100 times 0.12 = 12



EDIT: more info



lets say there is a band, 264 people and 132 want to quit. What percent want to quit? 264, move the decimal 2 to the left, so its 2.64 and divide 132 by 2.64 which is 50 or 50%
say there was a survey where they asked 20 people if they like pies. 4 said yes. 16 said no. to get the percentage you would do 4/20= .2, multiply your answer by 100 and you get 20 so 20% of people said they liked pies.
percentage is a fraction.

for example 12% is 12 divided by 100.

12/100 = .12 to get the % you multiply by 100
well, if there are 10 suitcases in DEAL OR NO DEAL and only 5 SUITCASES are winners, you do:



5 divided by 10

5/10

= 50% chance
kayy so say you got]

24 out 56 on your test. you divide 24 by 56. and there you goo. so for deal and no deal, he'll take the number of boxes, and his number of guesses :)
out 100 people 66 people will win the money.



100 / 66%= 66 peeps



12 people do not like pies.



100 / 12% = 12
