Question

I know this seems like a stupid question but how would you change 1/50 to a percent?

Answer 1

Multiply it by 2 to get 2/100. Now it is 2%.

Answer 2

yup 2%

Answer 3

I got dividing it by 100 but I figured that wasn't right

Answer 4

You don't literally divide 2 by 100. A whole consists of 100 parts, so a number over a hundred = that number in percentage.

Answer 5

the question says to give the answer to the nearest hundredth of a percent

Answer 6

yes so it is 2% or .02

Answer 7

Well, it wouldn't be 0.02 of a percent, though.

Answer 8

?

Answer 9

I didnt put percent where did you get that?

Answer 10

I didn't say you did, but KJ's question asks for the answer to the nearest hundredth of a percent.

Answer 11

In the United States approximately one child in every 10,000 is born with PKU a syndrome that affects individuals homozygous for the recessive allele. given this incidence what percent of the population are heterozygous carriers of the recessive PKU allele? give your answer to the nearest hundredth of a percent

Answer 12

BTW you can just call me Josie

Answer 13

it's 1/50 not 11

Answer 14

Sorry, yes, typo.

Answer 15

ok I'm trusting you. I have way too many other problems to do. I have like 30 pages due on the 8th. only have 1 done

Answer 16

Well, 1/50 is most definitely = to 2%. The question might just be messing with your head when it says to the nearest hundredth of a percent.

Answer 17

Way one: Divide the numerator by the denominator, and multiply it by 100 In your question: 1/50 = 0.02. 0.02 * 100 = 2.
Way two: Multiply the numerator and the denominator by a number that will make the denominator equal 100. In your question: 1/50: multiplying 50 by 2 would make the denominator equal 100. What ever you do to the denominator, you must do to the numerator. 1*2 / 50*2 = 2/100 When a fraction has a denominator of 100, the numerator is the percent: 2.

Answer 18

but I posted this question a while back and the person that answered gave me like 1.98%

Answer 19

Well, then, I would go with that. It sounds closer to the answer the question expects :)

Answer 20

but then I found this

Answer 21

Ok, having a look...

Answer 22

I'm so confused. there's so many different answers and I want to get this right

Answer 23

Now, I would go with 2%, as the genetic example agrees.

Answer 24

I don't really think the guy knows what he is talking about. but the website doesn't really give a percent related to the question

Answer 25

this is what he gave me
to solve for q, you take the squared root of both sides:

q 2 =1 10000 →q=1 10000 − − − − − − √ →q=0.01


so p=1-q = 0.99

2ab is the percentage of heterozygous individuals (i.e. carriers)

2(0.99)(0.01)= 0.0198

1.98 %

Answer 26

Ok, I am just going to try to work it out quickly, one sec

Answer 27

ok

Answer 28

Ok, just checking the values, p and p^2 = 1, and q^2 = 1/10000, correct? Just double checking my answer.

Answer 29

I don't have anything for p^2 but everything else looks right

Answer 30

Well, now I'm just confused too. However, on slide 33/34 of this, http://www.slideshare.net/zna79/population-genetics-aqa, the percentage is worked out to be 1.98%

Answer 31

I am very confused myself

Answer 32

:) - Sorry I can't clear up the confusion.
