Exercise 10 Page 59

The quotient of two integers with different signs is negative.

Type of sum: Integers with different signs
Sum: - 7
Is Sum Positive, Negative, or Zero? Negative

Practice makes perfect

Let's start by looking at the given table!

Expression Type of Quotient Quotient Quotient: Positive, Negative, or Zero
14÷(-2)
- 24÷12
- 55÷(-5)

We want to complete the first row of the table. We can see that we want to divide a positive integer, 14, by a negative integer, - 2. This means that we will find the quotient of two integers with different signs. We can add this information to the table.

Expression Type of Quotient Quotient Quotient: Positive, Negative, or Zero
14÷(-2) Integers with different signs
- 24÷12
- 55÷(-5)

Finally, we will calculate the given quotient. Remember that the quotient of two integers with different signs is negative.
