Question

Henry uses 3 feet of wood to make 3/4 of a birdhouse. If he has 12 feet of wood how many birdhouses can he make?

Answer 1

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 $\frac{3}{4}$ of a birdhouse.

So, in 1 feet of wood to make = $\frac{\frac{3}{4}}{3}$  = $\frac{3}{12}$

Thus, in 12 feet of wood = $\frac{3}{12} \times 12$  = $\frac{36}{12}=3.$

Therefore, he can make 3 birdhouses if he has 12 feet of wood.
