Trina's science club is building bluebird houses to put in the local park. For the first 1/6 dozen bird houses, Trina finds that they used 3/4 foot of wooden trim. Trina needs to buy enough wooden trim for one dozen bird houses . Write a unit rate that describes how much wooden trim Trina needs.

Answer:4.5 foot is needed for a unit dozen bird house Explanation:Given Tina saw ¾ foot of wooden trim is being used for  first 1/6 dozen bird houses Therefore, we can write as,4 1/6 dozen = ¾ foot For 1 dozen bird houses, we have to use the unitary method 1/6 dozen = ¾ foot  Therefore, 1 dozen or unit dozen = [tex]\frac{\frac{3}{4}}{\frac{1}{6}}[/tex]1 dozen = ¾ * 6 = [tex]\frac{9}{2}[/tex] foot = 4.5 foot  Therefore, 4.5 foot is needed for a unit dozen bird house
