Question

Write a real-world situation that is represented by the following inequality: −19 < 40. Explain the position of the numbers on a number line.

Answer 1

Situation: Water is liquid at 40°C above zero and it turns to ice at below zero temperatures. For example, water at 19°C below zero is frozen.

Explanation:

The integer that represents 19°C below zero is -19.

The integer that represents 40°C above zero is 40.

The attached number line shows that 40 is at the right of -19. So -19 < 40.
