A new playground was being built by volunteers. Twelve people were tasked with smoothing out the ground. Eight people were put on assembling the swing sets. Four people were put on assembling the see-saws. Eleven people were put on building mazes and five people were tasked with building sandboxes. Using a pie graph, which percentage were tasked with assembling swing sets?
