Understanding Measurements and Inequalities

This video tutorial covers comparing positive and negative numbers through various exercises. It includes determining the truth of inequality statements, selecting equivalent statements, ordering states by elevation, plotting numbers on a number line, calculating distances run in laps, and determining stadium capacity percentages.

Which of the following is true about the inequality -5 > 2?

• It is true because -5 is to the right of 2 on the number line.

• It is false because -5 is to the left of 2 on the number line.

• It is true because -5 is greater than 2.

• It is false because -5 is equal to 2.

Why is the statement 3 > -8 true?

• Because 3 is to the left of -8 on the number line.

• Because 3 is to the right of -8 on the number line.

• Because 3 is equal to -8.

• Because -8 is greater than 3.

Which statement is equivalent to -8.7 < -8.4?

• -8.7 is further to the right than -8.4.

• -8.7 is greater than -8.4.
