Worked practice questions
For integers p and q, when is p/q defined?
- q is nonzero
- p is nonzero
- p is positive
- q equals zero
Show answer and solution
Correct answer: A. q is nonzero
The denominator q must be nonzero for the quotient p/q to be defined.
Which fraction represents the integer -9?
- 1/9
- 9/1
- -1/9
- -9/1
Show answer and solution
Correct answer: D. -9/1
Dividing -9 by 1 leaves the integer -9.
