(12/25) * 1650 = 19,800/25 = 792

A hotel has 408 rooms. 9/17 of these rooms are for non-smokers. How many rooms are for non-smokers?

My answer was maybe 351/17.

You haven't given the number of rooms.

Multiply 408 times 9/17

Hint: since 9/17 is a little more than 1/2, you're looking for a number that's a little more than half of 408.

Is my answer to that 2nd question 221/17? I think I did something wrong.

When you multiply fractions, first multiply the numerators.

408 * 9 = 3672

Then multiply the denominators.

1 * 17 = 17

408 times 9/17 = 3,672/17

Divide:

3,672/17 = 216

Yes! 216 is a little more than half of 408.
