Question from Fadely: If 8 divided by 4/2 can be expressed as 8 X 2/4, how can 8 X 2/4 be converted back to 8 divided by 4/2? |
Hi,
To express
\[\frac{8}{\frac42} \mbox{ as } 8 \times \frac24\]
I would multiply the numerator and denominator by $\large \frac24$ to get
\[\frac{8}{\frac42} = \frac{8 \times \frac24}{\frac42 \times \frac24} = \frac{8 \times \frac24}{1} = 8 \times \frac{2}{4}.\]
To express
\[8 \times \frac{2}{4} \mbox{ as } \frac{8}{\frac42}\]
I would reverse the steps above.
