Question

what is the answer of 1/ab+1/bc+1/ca​

Answer 1

Answer:

$\frac{1}{ab} + \frac{1}{bc} + \frac{1}{ca}$

taking LCM of all denominators ab , bc and ca

so the LCM is ab,bc,ca

Now , do as we add common fraction taking LCM of all denominators then adding all.

So ,

$\frac{1}{ab} + \frac{1}{bc} + \frac{1}{ca} \\ \\ = \geqslant \frac{bcca \: + abca \: + abbc}{abbcca}$

Here it is the answer you can solve nore to take it in simplest form

$\frac{1}{ab} + \frac{1}{bc} + \frac{1}{ca}$

taking LCM of all denominators ab , bc and ca

so the LCM is ab,bc,ca

Now , do as we add common fraction taking LCM of all denominators then adding all.

So ,

$\begin{lgathered}\frac{1}{ab} + \frac{1}{bc} + \frac{1}{ca} \\ \\ = \geqslant \frac{bcca \: + abca \: + abbc}{abbcca}\end{lgathered}$

Here it is the answer you can solve nore to take it in simplest form
