Question

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 1

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 = $\frac{\frac{3}{4}}{\frac{1}{6}}$

1 dozen = ¾ * 6 = $\frac{9}{2}$ foot = 4.5 foot  

Therefore, 4.5 foot is needed for a unit dozen bird house
