A metal rod 9.4 meters long is cut into two pieces. One piece is 3 times as long as the other. Find the length of the longer piece in meters. Round your answer to the nearest tenth of a meter.
The smaller one is a quarter of the original ([tex]\frac{1}{1+3}[/tex]). That is, 2.35. The longer one is 3 times that: 7.05. Rounding gives us 7.1 meters.
