Hello,


I am looking for a solution to the following on a problem relating to CO2 emissions of transport.

I have the following:

[1+(7556*A)]/[1+(4.4*A)]

I want the result as a ratio, with the "A" values somehow multiplied out. Obviously I don't know what A is!

Is this at all possible?

Do you have a numerical value of the given expression, i.e.,

[1+(7556*A)]/[1+(4.4*A)] = M (where M is some number or expression like x/y)

I'm not clear what you mean by "solution to the problem". What is "the problem"? If that is equal to some number, and you want to solve for A, as Subhotosh Kahn suggests, then multiply both sides by 1+ 4.4A to get a linear equation in A.

If you want to get a single value for the fraction, with no A, that's not possible. For example, if A= 0, that is equal to "1". If A= 1, it is equal to \(\displaystyle \frac{7557}{5.4}\). if A= 2, it is \(\displaystyle \frac{7558}{9.8}\), all different numbers.

If, by "with the "A" values somehow multiplied out", you want some number times A, that is also impossible. As before, when A= 1, it is equal to \(\displaystyle \frac{7557}{5.4}\) so that is what the multiplier would have to be. But then the value at A= 2 would have to be\(\displaystyle \frac{7557}{5.4}(2)= \frac{7557}{2.7}\ne \frac{7558}{9.8}\).

I'm not sure what you want. As indicated above, it would help if we knew more about what you are trying to do. For example, if A were always 'large' then you could say that the ratio would always be about 1717. How good that 1717 is would, of course, depend on the actual value of A.
