A true mathematical statement is shown

11 7/20 < 20 3/4

Maggie used the statement above to conclude    -11 7/20  < -20 3/4

Determine if Maggie’s mathematical statement is correct and justify your answer.

• Maggie’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.

• Maggie’s mathematical statement is correct because the larger value will be farther from zero on a number line. In this case, - 20 3/4  is farther from zero.

• Maggie’s mathematical statement is incorrect because -11 7/20  is located to the left of - 20 3/4  on a horizontal number line. Therefore,  -20 3/4 is less than -11 7/20 .

• Maggie’s mathematical statement is incorrect because both numbers are negative, the larger value will be closer to zero. In this case, -11 7/20 is closer to zero.

An expression is shown.

|2 3/4|

Which statement best describes the expression shown?

• The |2 3/4| = 0 because the distance from 2 3/4  to -2 3/4  is 0

• The |2 3/4| = -2 3/4  because the distance from 2 3/4  to 0 is

  -2 3/4

• The |2 3/4| = 2 3/4  because the distance from 2 3/4  to 0 is

  2 3/4  

• The |2 3/4| = -2 3/4  because the opposite of 2 3/4 is -2 3/4
