    a) 14, 11, 10
    b) 28,11,10

    Convert to mole values using the formula weights of each element. Then compare using closest whole number ratios.

    You may need to do some common factor or common divisor operation to obtain that "whole number ratio" relationship.

    There will be 10 parts (grams or tons, or pounds, etc...) of N, 11 parts of P and 14 parts of K. Convert that to moles using units that you are familiar with.

    Hint: Don't use tons...
