Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.
The total hours that Cesar has used in practicing will be:
= 1 1/2 + 2 1/4 + 1 1/2
= 5 1/4
To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:
= 10 - 5 1/4
= 4 3/4 hours.
Cesar needs to practice for 4 3/4 hours more.

The division sentence using negative numbers where the quotient represents the number of questions Fred answered incorrectly on the test is 20 ÷ (-1) = -20.
Let "x" represent the number of questions Fred answered incorrectly on the test.
Since he got a score of 80, then the equation:
Total Questions - Incorrectly Answered Questions = Score
100 - x = 80
To create a division sentence using negative numbers, express this equation in a different form:
x = 100 - 80
Now, subtract:
x = 20
So, a division sentence using negative numbers is:
20 ÷ (-1) = -20
This division sentence represents that Fred answered 20 questions incorrectly on the test.
