For every $20 that a billionaire spends, a millionaire spends the equivalent of 20 cents. For every $8 that a millionaire spends, a yuppie spends the equivalent of $1. The ratio of money spent by a yuppie, millionaire, and billionaire can be expressed as  Answers:  A) 1 : 8 : 800  B) 1 : 4 : 100  C) 20 : 4 : 1  D) 100 : 4 : 1  E) 400 : 4 : 1
B.........M........Y   20.....0,20......Y   B.........8........1   What I did first was to turn 0.20 to 2 (by multiplying by 10), so that it is easy to find the LCM. This led me to this:   B.........M........Y   200.....2.........Y   B........80......10   Then I multiplied every row by 80 (the LCM of 2 and 80), which led me to this:   B.........M........Y   8000...80.......10   Then I got rid of the extra zero, and in the correct order this is Y:M:B=1:8:800   1 : 8 : 800NS 1 : 8 : 800
