Answer:
He can make 3 birdhouses if he has 12 feet of wood.
Step-by-step explanation:
Given:
Henry uses 3 feet of wood to make 3/4 of a birdhouse.
If he has 12 feet of wood.
Now, to find the birdhouses he can make.
So, to get the number of birdhouses we use unitary method:
Henry uses 3 feet of wood to make [tex]\frac{3}{4}[/tex] of a birdhouse.
So, in 1 feet of wood to make = [tex]\frac{\frac{3}{4}}{3}[/tex] = [tex]\frac{3}{12}[/tex]
Thus, in 12 feet of wood = [tex]\frac{3}{12} \times 12[/tex] = [tex]\frac{36}{12}=3.[/tex]
Therefore, he can make 3 birdhouses if he has 12 feet of wood.
