The teacher asked 4 students to measure 4 different objects. The table that follows represents their measurements. Which student had the largest percent error?

I actually know the table for those wondering. 1.) 50 in, 49 in (2.) 25 cm, 25.5 cm. (3.) 8ft., 7 1/2 ft (4.) 1.6 meters, 2.1 meters * the comma separates the actual length from the mesured length.
