On a winter day, the low temperature in Chicago, Illinois was 5 degrees below zero (in ∘C ) and the low temperature in Denver, Colorado, was 9 degrees below zero (in ∘C ). Sophia said, "The temperature in Chicago was colder than in Denver because -5 < -9." Which statement correctly describes Sophia's interpretation? Sophia is correct. -5 < -9 , so it is colder in Chicago than in Denver. Sophia is not correct. -5 < -9 , but the means it is colder in Denver than in Chicago. Sophia is not correct. -5 > -9 , so it is colder in Chicago than in Denver. Sophia is not correct. -5 > -9 , so it is colder in Denver than in Chicago.

Answer: Sophia is not correct. -5 > -9 , so it is colder in Denver than in Chicago.

Explanation:

Given the that :

Temperature in Chicago Illinois = 5°C below Zero

Temperature in Denver, Colorado = 9°C below Zero

5°C below 0 = 0 - 5 = - 5°C (Chicago)

9°C below 0 = 0 - 9 = - 9°C (Denver)

In the negative direction ( positions below 0)

- 5 is greater than - 9

For cold temperatures :

The lesser the negative value, the colder the temperature ; locations with higher value are less cold than those with higher values

Since ; (- 9 < - 5) or (-5 > - 9) then, city with - 9°C is colder than that with - 5°C

Hence, Denver is colder than Chicago
