30. While making a dessert, Jane used 9/10 of a scoop of brown sugar as well
as 1/2 of a scoop of white sugar. How
much more brown sugar did Jane use?

Jane used 2/5 of a scoop more of brown sugar than she did with white sugar.

Step-by-step explanation:

If you want to find how much more something is from something else, you subtract. So, subtract 9/10-1/2. If you want to subtract, they should both have the same denominator. So, 9/10-1/2 is the same as 9/10-5/10. 9/10-5/10 is equal to 4/10 which is simplified to 2/5.
