At 10:00 P.M. one winter night, the temperature was - 3°C.

Question

At midnight, the temperature was -7°C. Use <, >, or = to compare the two temperatures and explain their relationship.

Answer 1

To compare the two temperatures, we have:

• Temperature at 10:00 P.M.: -3°C
• Temperature at midnight: -7°C

When comparing temperatures, a higher number indicates a warmer temperature.

Since -3°C is greater than -7°C, we can express this relationship as:

-3°C > -7°C

This means that -3°C is warmer than -7°C. Therefore, the temperature decreased from -3°C to -7°C as the night progressed.
