Question

What is the approximate percent change in a temperature that went down from 120 degrees to 100 degrees?

Answer 1

Change in temperature=\frac{120-100}{120}120120−100​ 
Percentage change in temperature=\frac{20}{120} *10012020​∗100 
=16.67%

Answer 2

Answer:

Step-by-step explanation: deltaT/T×100 we have to do

Here deltaT is equal to the change in temperature i.e 120-100=20

Now we have to divide it by actual temperature i.e 120

So the final answer is 20÷120= 1/6

We have to find percentage so multiply by 100 therefore the final answer is 100×1/6= 16.66 so this is the percentage change approximately ...

16.66 is also similar to 16.7
