45 m. If each student needs 750 mm of tubing, the teacher should order 45 m of tubing.
a) Find the <em>length in millimetres</em>
Length = 60 students x (750 mm tubing/1 student) = 45 000 mm tubing
b) Convert <em>millimetres to metres </em>
Length = 45 000 mm tubing x (1 m tubing/1000 mm tubing) = 45 m tubing
The correct answer is C
