A temperature of -11 degrees is warmer than a temperature of -20 degrees.
True
In two negative numbers, the number which is closer to zero on the number line is greater than the other.
-11 is closer to 0 when compared to -20. Thus, -20 is less than -11.
Also, we know that greater the temperature, greater the warmth.
Therefore, a temperature of -11 degrees is warmer than a temperature of -20 degrees.
