A true mathematical statement is shown.

1.35 < 4.5

Isabella used the statement above to conclude -1.35 < -4.5

Determine if Isabella's mathematical statement is correct and justify your answer.

• Isabella’s mathematical statement is correct because if a positive number is larger than a second positive number, the relationship will hold true given the negative or opposite of the given numbers.

• Isabella’s mathematical statement is correct because the larger value will be farther from zero on a number line. In this case, -4.5 is farther from zero. 

• Isabella’s mathematical statement is incorrect because -1.35 is located to the left of -4.5 on a horizontal number line. Therefore, -1.35 is less than −4.5.

• Isabella’s mathematical statement is incorrect because both numbers are negative, the larger value will be closer to zero. In this case, -1.35 is closer to zero.
