Question

Jeremy uses 27 inches of board for each birdhouse he builds. How many yards of board does he need to make 6 birdhouses?

Answer 1

Answer:

$4.5\ yd$

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

$\frac{27}{1}\frac{in}{birdhouses}=\frac{x}{6}\frac{in}{birdhouses} \\ \\x=6*27\\ \\x=162\ in$

step 2

Convert inches to yards

$1\ yd =36\ in$

$162\ in=162/36=4.5\ yd$
