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