15 yd

#### Work Step by Step

Use a unit fraction with yard (the unit for your answer) in the numerator, and feet (the unit being changed) in the denominator. Because 1 yard = 3 feet , the necessary unit fraction is
(1 yard)/(3 feet)
Multiply 45 ft times the unit fraction
45 ft * (1 yard)/(3 feet) = 15 yard
