Best ResponseYou've already chosen the best response.0270 works because it's 18*15. Any number that both 18 and 15 go into works. I think 90 is the smallest. I think this is what you're trying to do\[\frac{ 270(x2) }{ 18 }=\frac{ 270(x3) }{ 15 }\] and then reduce the whole numbers \[15(x2)=18(x3)\] Which is exactly what you got when you cross multiplied
