Question 458450: One-fourth of the cars purchased at a dealership are luxury models. If 360 luxury models were purchased last year, how many total cars were purchased?
I first converted 1/4 into decimal which is 0.25, and now i dont know what to do. Do i multiply it with 360 which gives me 90 or do i divide it which will give me 1440? Both numbers show up on my multiple answer sheet. It confuses me. Someone plz clarify it for me.

There is no need to convert to decimal. Actually the fraction works better than the decimal.
Let's call the total number of cars x
One quarter of the total is 360
1/4*x=360
x=1440
Of course, both numbers are options.

You can put this solution on YOUR website! 1/4th of the cars were luxury, 360 total luxury cars were purchased last year, assuming that the ratio of luxury cars and regular cars sold were the same, then simply multiply 360 by 4 to achieve your "whole" fraction of cars
360 x 4 = 1440
or look at it this way, if 1/5 of the cars were luxury, and they sold 5 in the entire year, the total number of cars sold would be 25 make sense?
