A convenience store sells 1650 items where 12/25 of the items are junk food. How many of the items are junk food?
(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.
To find out how many items are junk food, you need to calculate 12/25 of the total number of items.
Step 1: Multiply the total number of items by the fraction 12/25.
1650 * (12/25) = (19800/25) = 792
Therefore, there are 792 junk food items in the store.
