OpenStudy (evoker):

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

OpenStudy (drummergirl7):

OpenStudy (drummergirl7):

So a and b are out! And c and d is left

OpenStudy (evoker):

C you could divide by 3 which gives 6:7, ah looks like a match

OpenStudy (drummergirl7):
