Work Step by Step

a) To convert in to cm, multiply by 2.54 because 1 in= 2.54 cm. $78.3 in×\frac{2.54 cm}{1 in}=198.882 cm$ b) To convert from yd to m, divide by 1.094 because 1 m= 1.094 yd . $445 yd×\frac{1 m}{1.094 yd}=406.908 m$ c) To convert from yards to km, multiply by 30.48 because 1 ft= 30.48 cm. $336 ft×\frac{30.48 cm}{1 ft}= 10241.3 cm$ d) To convert in to cm, multiply by 25.4 because 1 in= 25.4 mm. $45.3 in×\frac{25.4 mm}{1 in}=1150.62 mm$
