Landon needed to compare the absolute values of -12.6 and 12.78. He incorrectly said that the absolute value of -12.6 is greater than the absolute value of -12.78. How do you know that /-12.6/ < /-12.78/?
A.The distance from negative 12.6 to zero is less than the distance from negative 12.78 to zero.
B.The distance from negative 12.6 to zero is greater than the distance from negative 12.78 to zero.
Bonus question: What was Landon's mistake?
What is A.
Bonus Question answer: Landon compared the actual values instead of the absolute values.
