    Percentage problem ( a noob one)

    Say e.g. we have 10 cats. 1 white, 2 black, 2 brown, 1 blonde. 2 black-white, 1 brown-white, 1 blonde-white. I want the percentage for each of 4 colors (white, black, brown, blonde), with a simple explanation
    Thanks in advance.

    Divide the number of cats of each color, then divide by the total number of cats. Finally, convert from a decimal to a percentage- multiply by 100 and append the "%" sign.

    For example, there are 2 black cats out of 10: \frac{2}{10}= 0.20 which is 20%

    To be honest, I know how to find this simple percentage ratio as shown above. My problem is: eg.black color is found on 4 cats (you missed 2 double color cats ). So if we do the above calculations: white 5/10, black 4/10, brown 3/10, blonde 2/10 we have a 140% total! Its wrong, isnt it?
