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

She can paint 6 rooms.

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,
`(3)/(2)` cans of paint is needed to paint 1 room.

Then, 1 can of paint is needed to paint =
`(1)/((3)/(2)) =(2)/(3)` room.

Thus, 9 cans of paint is needed to paint =
`(2)/(3) * 9`

`=(18)/(3) \\\\=6\ rooms.`

Therefore, she can paint 6 rooms.
