Step-by-step explanation:

Adam is building birdhouses that requires $\frac{1}{2}$ i.e 0.5 feet long boards.

Now, he has an $8\dfrac{1}{4}$ i.e. 8.25 feet longboard and wants to cut each 0.5 feet longboards.

We have to calculate the number of pieces of exactly 0.5 feet length that can be made from this 8.25 feet longboard.

Now, $\frac{8.25}{0.5}= 16.5$

So, there can be 16 whole board of exact length 0.5 feet. (Answer)
