Final answer:
Each piece of material is approximately 3.3 yards long.
Step-by-step explanation:
To find the length of each piece, we divide the total length of the material by the number of pieces. Mrs. Jones bought 50 yards of material and cut it into 15 pieces. Therefore, each piece is:
50 yards ÷ 15 pieces = 3.33 yards
So, each piece is approximately 3.3 yards long to the nearest tenth of a yard.
