    Quick Question re: adding percentages

    Hello- first time poster...

    How do I add two % together?

    i.e. I have two products. One is reporting 41% of total usage. The other is reporting 32% of total usage.

    How do I find what the total usage is between the two?

    Thanks in advance.

    In general, percentages represent parts of something.

    Here, the "something" is the "total usage".

    Let x represent the "total usage".

    You have 41%x, that is to say \frac{41}{100} x and 32%x, that is to say \frac{32}{100} x.

    So logically, the sum of the two will be \frac{41+32}{100} x, =73% x.

    Now it depends on whether the percentages are observed for independent things... We have to see what the situation is !
