Find the big picture: How long will it take to saw a pole into five pieces?

Solution:

1. first we need to find out how long it takes to saw a pole. To do this we need to divide 12 by 3 because it took 12 minutes to saw a pole into three pieces. 12 divided by 3 equals 4.

2. Now we know that it takes 4 minutes to saw one piece. But because we need to saw a pole into 5 pieces, we need to add on 4 minutes to make 4 pieces, which equals 16 minutes, and then another 4 minutes to make 5 pieces. Which equals 20 minutes.
