Answer:

19.04%

Step-by-step explanation:

The temperature decreases from 21°C to 17°C.

We need to find the percentage decrease in the value of temperatures.

The percentage decrease in any value is given by :

[tex]\%=\dfrac{|\text{initial value-final value}|}{\text{initial value}}\times 100\\\\=\dfrac{21-17}{21}\times 100\\\\=19.04\%[/tex]

So, the required percentage decrease is 19.04%.
