Best ResponseYou've already chosen the best response.0Whenever you say `some fraction OF some number', you can multiply the two together to get your number. So, in this case: 3/5 OF 30 means: \[\frac{3}{5}\times 30\]

Best ResponseYou've already chosen the best response.0Hehe, sorry for abandoning you there for a minute. That was the equivalent of: \[\frac{3}{5}\times \frac{30}{1}\] So you can multiply the 3 across and keep the 5, then do the division.

Best ResponseYou've already chosen the best response.0Yes, it is. \[\frac{3}{5} \cdot \frac{30}{1} = \frac{3 \cdot 30}{5 \cdot 1} = \frac{3 \cdot 6}{1} = \frac{18}{1} = 18\]
