**Bosnian**, Saturday, February 12, 2011 at 1:54amR=Regular coffee

F=Flavored coffee

R=3*F

R+F=8/9

3*F+F=8/9

4F=8/9 Divide with 4

F=(8/9)/4=8/(9*4)=8/36=(2*2*2)/(2*2*9)=2/9

F=2/9

R=3*F

R=3*(2/9)=3*2/(3*3)=2/3

R=2/3 F=2/9

R+F=(2/3)+(2/9)=[2*3/(3*3)+(2/9)]=

(6/9)+(2/9)=8/9

**coursonc**, Sunday, August 28, 2011 at 2:29amFirst off, 8 out of 9 customers ordered coffee, not 8/9 of a customer, as that doesn't make sense, (maybe one customer forgot his wallet, lol)customers are whole numbers and not fractional, use your brain.

So: R+F=8 and,

3F=R, thus substituting 3F for R,

3F+F=8 or 4F=8 or F=2

If F=2, then R=6 since 3(2)=6

Since the question is asking not the total number of customers ordering flavored coffee,(which is 2) but what FRACTIONAL part of the customers total(which is 8) that ordered flavored coffee, the answer would be 2/8 or 1/4 of the customers.
