Couple of ways to check this one way would be to see what has the same decimal representation, or Try putting each in lowest terms.
OpenStudy (drummergirl7):
Ok, so how do I put them in the lowest terms. Sorry I am really bad at math :(
OpenStudy (evoker):
Basically divide out anything they have in common so for instance 24 and 28 are both divisible by 4 yielding 6:7
OpenStudy (drummergirl7):
Ok
OpenStudy (evoker):
A is all ready reduced
B would reduce by dividing by 4 to 3 : 4
