Another mid level math question about %.

Question

$A = 1000, B = 0.6$

$Y \times B = A ; (? \times 0.6 = 1000)$

Need to find $Y$ every time I change $A$ or $B$. How do i ask a calculator to do that (: ?

(I managed to reverse engineer a way from another answer by René Richter - which is)

$(1 / B) \times A$

Any other obvious ways to calculate this that I'm missing? Yes i know its probably pitiful, but a headache and silly math skills only get so far ...

Thx in advance. Thx in advance.

Answer 1

I'm not very sure what you are trying to accomplish here:

if $$Y = A/B $$

Then if you change B, simply divide it by your value of A to find Y.

Similarly if you change A, you would follow the same process.
