Question 12 • Grade 7 Mathematics

Frida applied the steps to find the product of negative 1 point 2 times negative 9 point 4 Frida's Work Step 1: negative 1 point 2 times negative 9 point 4 is equal to negative 9 point 4 times negative 1 point 2 Step 2: is equal to negative 9 point 4 times negative 1 plus negative 9 point 4 times negative 0 point 2 Step 3: is equal to 9 point 4 plus 1 point 8 8 Step 4: is equal to 11 point 2 8 Which step shows where she applied the property that states multiplying two negative numbers will always yield a positive number?

Answer
A
During Step 1
B
Between Step 1 and Step 2
C
During Step 4
D
Between Step 2 and Step 3

Explanation

Between Step 2 and Step 3, Frida changes each product of two negative numbers into a positive number: (−9.4)(−1) becomes 9.4, and (−9.4)(−0.2) becomes 1.88. This uses the rule that multiplying two negative numbers gives a positive product. Therefore, the correct choice is D, “Between Step 2 and Step 3.”
