Question

Gloria has 2 5/8 ounces of perfume. If she uses one third of it, how much will she have left?

Answer 1

For this, we need to convert the mixed number into a fraction and multiply by 2/3 because thats how much is going to be left if 1/3 is used.

`2 (5)/(8) = (21)/(8)`
Now multiply

`(21)/(8) * (2)/(3) = (42)/(24) = (21)/(12)`
Now if you want that into a mixed number we get

`(21)/(12) = (12)/(12) + (9)/(12) = 1 (9)/(12)`
1 and 9/12 ounces will be left after 1/3 is used.
