425g * 1ml/.92g ≈ 461.957 ml

Something that people often do not understand is that you can cancel units just the same as you can cancel numbers!

This is what you have.    

$$\frac{425g}{1},\quad \frac{0.92g}{1ml} \qquad \mbox{ and you want to find a volume which is mL}\\\\
\mbox{Put the mL first and on the top}\\\\\
\frac{1ml}{0.92g}\times \frac{425g}{1}=\frac{1ml\times 425}{0.92\times 1}=462ml\quad \mbox{to the nearest ml}\\\\$$

NOTE: 

1) The grams cancelled out.

2) When fractions have units it is alright to turn them upside down.

for example 5km/1hour is the same as 1 hour/5 km
