If p/5 = r/2 and r = 0.75s, what is the ratio of p to r to s?
Choose the correct choice from the following choices:
A) 2 : 3 : 4  B) 8 : 12 : 9  C) 15 : 6 : 8  D) 6 : 4 : 3  E) 12 : 8 : 3
p/5=r/2, r=0.75s, what is p:r:s?   we get p/r=5/2 and r/s=3/4, so   5/3*3/2 and 2/2*3/4   15/6 and 6/8   15 : 6 : 8
