Question

It takes 1/3 pint of paint to cover a birdhouse. There are 12 and 1/3 pints of paint in a can. Write and evaluate a division expression to find the number of bread houses that can be painted.

Answer 1

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 $\frac{1}{3}$ pints of paint, we can paint = 1 birdhouse

By using 1 pints of paint, we can paint = $\frac{1}{\frac{1}{3} }=1\times3=3\ birdhouses$

By using  $12\frac{1}{3}$ pints of paint, we can paint $=3\times12\frac{1}{3}$

                                                                   $=3\times\frac{12\times3+1}{3} \\\\ =3\times\frac{37}{3} \\ \\ =3\ canceled \ by\ 3\\=37\ birdhouses$

Thus, 37 birdhouses can be painted by using $12\frac{1}{3}$ pints of paints.
