    Question Mass/Mixing Formula Needed

    Need some quick help.
    252 g = 63% of the total mass (100%)
    With only knowing that, what would be 37% and what would be the total 100%?
    Thanks In Advance !!

    this what i think, tell me if it matches with the answer in the book

    252/63 divides evenly (4)
    this should mean the value of every percent is 4
    therefore, 37*4=148
    and 100*4=400

    there is another, more common way to do it

    252/.63=400
    then multiply 400 by .37 to get the percent of 37
    400*.37=148
