I'm assuming that you want to divide the fraction 23/0.3 by the fraction 20/24.
First of all, the fraction 20/24 can be simplified, since both numerator and denominator are multiple of 4:
![(20)/(24) = (5)/(6)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/pk110lra3mrb4kromcnnzugphj7hfzgypn.png)
Secondly, dividing by a fraction is the same as multiplying by the inverse of the fraction, i.e. if you have to divide by a/b, it's the same as multiplying by b/a.
So, we have
![(23)/(0.3) / (5)/(6) = (23)/(0.3) * (6)/(5)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/qg926khmq5n8d219jm4h46b80j1at7nh9n.png)
We can cross simplify 6 and 0.3 to have
![(23)/(0.3) * (6)/(5) = (23)/(0.1) * (2)/(5) = (46)/(0.5) = 92](https://img.qammunity.org/2019/formulas/mathematics/middle-school/2isz6hiwn323lpzaq391vwez3kbmas8dhw.png)
