Points A, B, C, and D lie on a line, in that order. If AB=2 units, BC=5 units and AD=14 units, what is the ratio of AC to BD? Express your answer as a common fraction.

From looking at this, we can see that

CD  =  14 - (2 + 5)

CD  =  7

And...

AC  =  2 + 5  =  7

BD  =  5 + 7  =  12

So, the ratio of AC to BD   =   $$\frac{AC}{BD}$$   =   $$\frac{7}{12}$$
