A land owner donates three acres of land to the city. The mayor of the city uses one acre of the land for a playground and the rest of the land for community garden plots. Each garden plot is 1/3 acre. How many plots are there?

Answer: 6 plots

Step-by-step explanation:

Since the mayor uses one of the three acres for a playground, we now have 2 acres left. Since each plot is one third of an acre, we know we can fit three plots into each acre. We have two acres, so 3x2=6. We have 6 plots.
