Answer:
[tex]4.5\ yd[/tex]
Step-by-step explanation:
step 1
we know that
Jeremy uses 27 inches of board for each birdhouse
so
by proportion
Calculate how many inches of board does he need to make 6 birdhouses
[tex]\frac{27}{1}\frac{in}{birdhouses}=\frac{x}{6}\frac{in}{birdhouses} \\ \\x=6*27\\ \\x=162\ in[/tex]
step 2
Convert inches to yards
[tex]1\ yd =36\ in[/tex]
[tex]162\ in=162/36=4.5\ yd[/tex]
