It is: 13+4+3+12 = 32 and 32/4 = 8 which is the mean average
32/12 in decimal = 2.6667 32/12: = 32 ÷ 12 = 2.6667 in decimal
-44
0.375
It is: 12--32 = 44 which is the same as 12+32 = 44
384/32 = 12
32 = (12/100)*x 32*(100/12) = x 3200/12 ~= 266.67
The average size is a 32 A or 34 A but if you are bigger or smaller its just how your body is growing
divide both 12 and 32 by 4 ; 12/ 4 = 3 32 / 4 = 8 . hence ; 12 / 32 = 3/8 .
