Hi, I was redoing some quizzes to try to get higher scores when I found this problem. The initial temperature, as I have seen it to be, is around 22.5, and the final temperature is 28. 28-22.5 is 5.5, but since it is subtraction, shouldn't it be it be in minimum decimal places so that the correct answer is 6? Thanks, Siddharth.

Your answer is correct.
In addition and subtraction ,follow the minimum decimal rule. So answer is 6 ⁰ C

Thank you! However, the quiz is selecting the correct answer as 5.5. I just wanted to let you know so you could fix it later.

Okay
I will check.
