Problem
A bar graph shows the number of hamburgers sold by a fast food chain each season. However, the bar indicating the number sold during the winter is covered by a smudge. If exactly 
of the chain's hamburgers are sold in the fall, how many million hamburgers are sold in the winter?

of the total number of hamburgers sold, so we can say that...
The answer is 2.5, or
