Ok so find the median so put the numbers in order so 82,83,84,85,85,86,86,86,87,87,88,89,90 then start from both sides cross off from both dies at the same time 83,84,85,85,86,86,86,87,87,88,89
84,85,85,86,86,86,87,87,88
85,85,86,86,86,87,87
85,86,86,86,87
85,86,86,86
86,86
so... 86 is the answer. i know its long but its the whole work hope it helped.
It can be helpful to remember that "%" is just a shorthand way to write "/100" (divided by 100, or per 100, or per cent). ("Cent" is often used to refer to 100 or 1/100. A "cent" is 1/100 of a dollar, or 1/100 of an acre, for example. A <em>cent</em>ury is 100 years.)
Make the denominator of your fraction be 100. Multiply numerator and denominator by 20/20.
