Question

student name: \t\t\t\t\tclass name: m/j grade 001 - pablo m mora vi
number of questions: 5 \t\t\tinstructor name: mora v
question 1 of 5
evaluate the following.
-27 ÷ 9 = □
-2 × (-9) = □

Explanation:

Step1: Evaluate \(-27 \div 9\)

Recall the rule for dividing a negative number by a positive number: the result is negative. And \(27\div9 = 3\), so \(-27\div9=-3\).

Step2: Evaluate \(-2\times(-9)\)

Recall the rule for multiplying two negative numbers: the result is positive. And \(2\times9 = 18\), so \(-2\times(-9)=18\).

Answer:

For \(-27\div9\), the answer is \(-3\); for \(-2\times(-9)\), the answer is \(18\).
