For every $10 that a billionaire spends, a millionaire spends the equivalent of 20 cents. For every $4 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 : 4 : 400
B) 1 : 4 : 100
C) 20 : 4 : 1
D) 100 : 4 : 1
E) 400 : 4 : 1
B.........M........Y   10.....0,20......Y   B.........4........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:   1 : 4 : 100.........M........Y   100.....2.........Y   1 : 4 : 100........40......10   Then I multiplied every row by 40 (the LCM of 2 and 40), which led me to this:   1 : 4 : 100.........M........Y   1000...40.......10   Then I got rid of the extra zero, and in the correct order this is Y:M:1 : 4 : 100=1:4:100   ANS 1 : 4 : 100
