4 bags of rice can feed 80 people for 12 days. What is the least number of bags of rice that must be bought to feed 300 people for 7 days.

Set up ratios using bags of rice as variable.
If 4 bags feed 80 people for 12 days, then 1 bag will either feed 20 people for 12 days or 80 people for 3 days.
Setting up ratio,
12/20 = 7x/300
7x = 3600/20
7x = 180
x = 25 5/7
Minimum is 26 full bags.
