Answer:
37 birdhouses
Step-by-step explanation:
Given:
It takes 1/3 pint of paint to cover a birdhouse.
There are 12 1/3 pints of paint in a can.
Question asked:
Write and evaluate a division expression to find the number of bread houses that can be painted.
Solution:
We will solve it by unitary method:
By using [tex]\frac{1}{3}[/tex] pints of paint, we can paint = 1 birdhouse
By using 1 pints of paint, we can paint = [tex]\frac{1}{\frac{1}{3} }=1\times3=3\ birdhouses[/tex]
By using [tex]12\frac{1}{3}[/tex] pints of paint, we can paint [tex]=3\times12\frac{1}{3}[/tex]
[tex]=3\times\frac{12\times3+1}{3} \\\\ =3\times\frac{37}{3} \\ \\ =3\ canceled \ by\ 3\\=37\ birdhouses[/tex]
Thus, 37 birdhouses can be painted by using [tex]12\frac{1}{3}[/tex] pints of paints.
