Hi everyone so I have a math question.

There is a share for 4 individuals.

Individual 1: 4712.50
Share 1: 333.35

Individual 2: 525.00
Share 2: 35.98

Individual 3: 4137.50
Share 3: 291.54

Individual 4: 1825.00
Share 4: 123.32


Just wondering what formula was used to find the share for each individual

Thank you.
 
It would help a lot if you told us what the two values labeled "Individual" and "share" mean!

It doesn't have a meaning.

Individual is the number(total, sum, whatever word you wanna use)

Than

Share is the Share taken from the total of the individual.


Hopefully that makes sense.


Basically what arithmetic did they use is what I'm asking.

Thanks.

This cannot be the problem assigned to you. Please post the problem - exactly - as it was assigned to you.
 
… Individual is … total, sum, whatever word you wanna use …
If the smaller numbers are percentages of the larger numbers, then we could use the word 'Whole'. The smaller number is a Part of the Whole.

To calculate the individual percents, divide each Part (small number) by its Whole (larger mate) and multiply the result by 100. (The four percents are all different, but if you round each of them to an Integer, then each Part is 7% of the Whole.)

However, there's not enough information given to determine whether the smaller numbers are actually percentages of the Wholes. This is because many different formulas will generate the smaller numbers, given the larger numbers. It could also be that the larger numbers were generated by the smaller numbers, instead of the other way around.


… what arithmetic did they use …
I've guessed that the smaller numbers are percentages of the larger numbers, but you should ask the person who did the arithmetic, to be sure.

Thank you.

You are asking for "the formula" that produces these results:

input
output
4712.50333.35
525.0035.98
4137.50291.54
1825.00123.32

When I put the data into Excel and make a trendline, I find that it is approximately linear (though not merely proportional); a quadratic function comes closer, but still not exact.

So the answer is that we can't know what formula was used to get these exact numbers, but we can make reasonable approximate guesses.

The next question is, why do you want to know? If you want to apply the same function to new inputs, then if they are within the region of the given inputs (interpolating), and you don't need to be accurate to the nearest whole number (much less the nearest cent, if this is money), then you might be safe. But if you use much larger numbers (extrapolating), or need precision, then you will just have to ask the source. Math can't read minds.
 
4712.50 / 333.35 = 14.137
4137.50 / 291.54 = 14.192
1825.00 / 123.32 = 14.799
525.00 / 35.98 = 14.591

If you look at the 1st 3 cases, you see a % increase as the amounts decrease.
Then the last case goes the other way!
So, makes completely no sense...
