Work Step by Step

To find the height of the tallest person in centimeters. The tallest person according to table is Robert Wadlow (1918–1940) USA whose height is 2.72 m Put the unit for the answer (centimeters) in the numerator of the unit fraction; put the unit you want to change (m) in the denominator. Unit Fraction equivalent to 1 = (100 centimeters)/(1 meter) Multiply 2.72 m times the unit fraction. 2.72 m * (100 centimeters)/(1 meter) = 272 cm Therefore the height of the tallest person in centimeters is 272 cm To find the height of the tallest person in millimeters. Put the unit for the answer (millimeters) in the numerator of the unit fraction; put the unit you want to change (m) in the denominator. Unit Fraction equivalent to 1 = (1000 millimeters)/(1 meter) Multiply 2.72 m times the unit fraction. 2.72 m * (1000 millimeters)/(1 meter) = 2720 mm
