# Thread: Real Simple Fraction Question

1. ## Real Simple Fraction Question

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:

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

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 $30$:

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

So is it appropraite to write that?

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

It's hard to explain it here but the thing is whether can i write that fraction? It's it mathematically correct?

6. 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.

7. 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.
*Thanked

8. 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.
