  1. % anything actually is parts per hundred; i.e., how many somethings you have in 100 total.
    If we had 6 toys and 3 were wagons. we would have 50% wagons. That is
    % wagons = (# wagons/total toys)*100 = 50%.
    Or if there are 75 people in a room and 25 of them are men and 50 are women we have
    % men = (#men/total people)*100 = (25/75)*100 = 33.3% and % women is (50/75)*100 = 66.7%.
    mass apples = 42
    mass oranges = 96
    Total mass is 42 + 96 = 138
    Then %apples = (42/138)*100 = ?
    % oranges = (96/138)*100 = ?
    Note the the percentages always adds up to 100% if everything is included.
