i don't understand why you times everything by 12? I get that it's the least common denominator so are you trying to find the least common denominator of the numbers that have a variable after them or what?

yes 12 is the lcm of 2,3,4. you don't need to do that, but this is one way to solve it and it makes our job easier, at least for me..
