    Question Expressing a comparison

    Dear teachers,
    I need to express a comparison between two experimental treatments: A and B. For instance, 25% increase in nitrogen levels has happened in treatment A. Therefore, is the following sentence true?
    The nitrogen level in treatment A has increased 25% to the treatment B.
    If this sentence is not true, how should I explain this comparison?
    Thank you.

    However, please note that this comparison is only valid if the original nitrogen levels of both A and B were the same, and it was only increased in A in order to compare the results.

    Dear Charliedeut,

    Thank you for your kind attention as well as your answer.
    Can I know your opinion about the following sentence?
    The nitrogen level in treatment A has increased by 25% compared to the treatment B.

    Thanks again.

    You haven't given enough information. What are the nitrogen levels of both samples before treatment? What are the levels after treatment A and treatment B? You've told us nothing about B.

    Here's a quiz for you. I have two bags. One has $5 in it. How would you compare the amount in each bag?
