numbers p and q?

b. p - q

c. p multiplied by q

d. p divided by q​

Answer 1

answer is b p-q .it the following

Answer 2

a. p + q

p + q cannot be a positive number for ANY two NEGATIVE rational numbers p and q.

p+q

• For any two negative numbers p and q, the addition also results in a negative number.
• For example, (-2)+(-4) = -6

p-q

• For any two negative numbers p and q, the subtraction results in a positive or a negative number.
• For example, (-2)-(-4) =-2+4= 2
• or else (-4)-(-2) = -4+2 = -2
• For subtraction, the resulting number is not always a positive number. But the result may be a positive number.

p*q

• For any two negative numbers p and q, the multiplication results in a positive number.
• For example, (-2)*(-4) = 8
• (-) * (-) =(+)

p÷q

• For any two negative numbers p and q, the division results in a positive number.
• For example, (-2)÷(-4) = 1/2
• (-4)÷(-2)=2

Hence, the answer is p+q
