Can i write 1/(1/30) ?

*/ = Divide

So it's something where by 1 divided by 30 first (1/30), then divided by 1 (1/).

Thanks for helping

You have:

$\displaystyle \dfrac{1}{\left(\frac{1}{30}\right)}$

Multiplying top and bottom of a fraction by the same thing leaves the value of the fraction unchanged, so here multiply top and bottom of the large fraction by $\displaystyle 30$:

$\displaystyle \dfrac{1}{\left(\frac{1}{30}\right)}=\dfrac{(1)\ti mes 30}{\left(\frac{1}{30}\right)\times 30}=\dfrac{30}{1}=30$

What I fail to understand... is why would you want to write $\displaystyle \dfrac{1}{\left(\frac{1}{30}\right)}$

You can do that, yes.

Is it possible that you elaborate on what are you doing, maybe? If not, then that's okay.

If you have such a fraction, you can simplify it as CB showed you. - Jan 16th 2011, 02:37 AMFailInMaths
Thanks for the answer. Really really apreciate it.

It's hard to explain it here, it's kinda complicated but i just only want to know whether it is mathematically correct.

It is certainly mathematically correct, but every complex fraction can be simplified to a simple fraction. There aren't many cases where someone would want to leave a final answer as a complex fraction.
