If two fraction add up to 1, what is the relation between their denominators? Are their denominators equal?
If $\frac{a}{b}+\frac{c}{d}=1$, then, is what is the relation between $b$ and $d$?
I was working on a problem. To solve the problem i need to know the relation between the denominators of fractions which add up to 1. I have tried to find out a relation by using the given equation but i could not obtain any useful result. I have searched the internet but could not find any help.
Note that $$1-\frac ab=\frac{b-a}b $$
