Hi this is probably really simple but if could some one could help this would be nice

6.25 -38 = 7-33.93

they are just ratios but I would like to know what the second unit should be if the first number is 9

eg 9-xxx = 6.25-38= 7-33.93

PLEASE, please read

You have not got any helpful answers because (a) you have not done anything that we ask that you do before posting, and (b) your question makes no sense. You say your question is about ratios, but your equation seems to involve subtraction. Did you know that ratios are usually writen either as fractions or using colons?

I am

**guessing** that you are saying 6.25 : 7 :: 33.93 : 38 or, what is the same thing, 6/7 = 33.93/38.

If that guess is right, I should point out that ratios are usually shown with positive integers so the normal way to express this is 625/700 = 3393/3800. More importantly, it is only

**APPROXIMATELY** true.

\(\displaystyle \dfrac{3393}{3800} = 0.8928947 \ne 0.8928571 = \dfrac{625}{700}.\)

Now if I am anywhere close to what you are talking about, let us know. And, given that you posted this in intermediate algebra, is your question

\(\displaystyle \dfrac{625}{700} \approx \dfrac{x}{900} \text { or } \dfrac{625}{700} \approx \dfrac{900}{x} \text {?}\)

EDIT: I see that while I was writing, Dr. Peterson made a guess similar to mine but probably more complete. Please answer our questions so we can be more helpful.
