Mariyam, a marine biologist, measures the length of a great white shark at 4.5 m long and its teeth at an average of 50 mm long. She wants to convert both measurements to centimeters.

Since 1 meter equals 100 centimeters, 4.5 m = 4.5 × 100 = 450 cm. Since 10 millimeters equal 1 centimeter, 50 mm = 50 ÷ 10 = 5.0 cm. Therefore, choice C, “shark length: 450 cm; teeth: 5.0 cm,” is correct.
