Answer:
The temperature today has decreased by 3°C.
Solution:
Subtract the yesterday's noon temperature and today's noon temperature.
Given:
30 °C
27 °C
So 30 °C - 27 °C is 3°C
So the technique in solving this problem is
to subtract the previous day's temperature and today's temperature to see if the temperature decreased or increased, and also you will know how many degrees Celsius did the temperature increase/decrease.
Hope it helps :D
