    amount  %   total    --------------------------------             5990    12% =718.8         4999    10% =499.9         5060    6%  =303.6         15000   7%  =1050 -------------------------------- total   31049   35% =2572.3 -------------------------------- =   31049   35%  =10867.15

well cant add percentages did taking portions of something, of them bigger others. simple way of seeing applying same logic using 100% if add 4 times 100% 4 times original value!

another way see percentages view them add fractions 50% x/2 or 33% x/3 way can remember way add fractions have common multiple of them (commonly minimum common multiple) after finding can add fractions.
