Question

Maya decided to paint some of the rooms in her hotel. She found out that a room required 3/2 cans of paint. If Maya buys 9 cans of paint, how many rooms can she paint?

Answer 1

Answer:

She can paint 6 rooms.

Step-by-step explanation:

Given:

Maya decided to paint some of the rooms in her hotel. She found out that a room required 3/2 cans of paint.

If Maya buys 9 cans of paint.

Now, to find the rooms she can paint.

So, we use unitary method to get the number of rooms:

If,  $\frac{3}{2}$ cans of paint is needed to paint 1 room.

Then, 1 can of paint is needed to paint = $\frac{1}{\frac{3}{2}} =\frac{2}{3}$ room.

Thus, 9 cans of paint is needed to paint = $\frac{2}{3} \times 9$

$=\frac{18}{3} \\\\=6\ rooms.$

Therefore, she can paint 6 rooms.
