what fraction came from investment

I had expressed that I knew that somehow 7 could be turned into 1 over 7 or 1/7
but did not know how to do that. That was the only thing I had said. You can look back to my answer and check it.
Then I got confused with something jomo wrote about converting to percentage. That is all.
 
But now I know why.
To turn an integer into a fraction, we merely write it in the numerator with a 1 in the denominator. Just that
 
Instead of saying that you got confused about something I said, why not just state what is confusing you.
100% = 100/100 = 1. That is 100% equals 1. Pick any number, say .4. Now .4 = .4*1 = .4*100% = (.4*100)% = 40%. That is multiply .4 by 100%. To convert any number to a percentage, you multiply by 100%.

Now right or wrong, you thought that the fraction was 7. Now 7 = 7*100% = 700%. That is, 7 does NOT equal 7%!. 7 = 700%.

I did not mean it the wrong way. I simply said that I did not understand your statement. I had gotten 7 as a result of a division I performed and the multiple choice answer only had 1/7 listed.
I asked how to turn the 7 into 1/7.
 
Okay, thanks. I understand now. And I stated three times what was confusing me. ?

You turn 7, which equals 7/1, into 1/7 by taking the reciprocal.

My question is why do you want to take the reciprocal? You thought, right or wrong, that you divided correctly, so why take reciprocals??

I simply said that I did not understand your statement. Yes, that is what you said. You also said that you stated three times what was confusing you. Did you state it somewhere other than this forum?
 
I did. At post #17, 18, 19, 22
I was stating there where my confusion lied. But Prof jomo. It is okay. I don't want to be argumentative. I appreciate your help ? and you all know that.

This is the explanation
I was looking for. Thank you. I wanted to take the reciprocal because 1/7 was listed as one possible choice.

The correct answer is

[math]\dfrac{56000 - 48000}{56000} * 100\% = \dfrac{8 * 1000}{56 * 1000} * 100\% = \dfrac{1}{7} * 100\% \approx 14.29\% \ne 7\%.[/math]
Where are you confused?

This may seem off topic, but a lot of mathematics is learning to think clearly BEFORE calculating anything. In this case, the statement of the problem may have been bad. But it makes no sense to say A’s earnings were 24000 as were B’s earnings, and their aggregate earnings were 56000. What were the EXACT words of the problem?

Response # 6 has a photo copy of the problem.
 
Yes. 1/7 was among the multiple choice answers. That is why I wanted the 7 expressed as a fraction but was not sure how to convert 7 into 1/7.
I should have listed the choice.

This shows a profound misconception.

Seven and one-seventh are DIFFERENT numbers. When you want to express 7 as a fraction, 1/7 does not do it. When you calculated 8000/56000, you were correct. That simplifies to 1/7, not 7. The number seven is simply not relevant to this problem at all.

Their aggregate earnings??. That is your statement, Jeff. That is not what the problem I posted says.
It says two members earn 24, 000 thousands each. And that the total annual income for the family was 56,000. And that the extra earning came from investment.

I know you all are hopping from forum to forum and sometimes answer/check things on the fly. I understand. But at least you answer all questions

That was my doubt all along. Thank you then.
 
I have done your calculations on paper now and yes it is 1/7.
I made a mistake when I performed the division.. I did it the wrong way.

Right at the beginning exactly at # 4 I expressed what was impeding me to go on with the problem. POST#4. And exactly at post # 5 I went awry

The fraction that is investment is 8,000/56,000 or 1/7. To convert to percentage you multiply 1/7 by 1 using 100% for 1.

Now I understand what jomo said here. At the moment I was confused.
the fraction that is from investment is 1/7!.
