Best ResponseYou've already chosen the best response.0x = time to fill a whole tank \[\frac{ \frac{ 1 }{ 12 } }{ \frac{ 1 }{ 3 } }=\frac{ 1 }{ x }\]

Best ResponseYou've already chosen the best response.01/3 * 12 hours because if you think about it, 1/12 of a tank only takes 1/3 of time to fill, so you can then multiply 1/3 by 12 to get how long it will take to fill 1 tank.
