add all the numbers together and divide by how many numbers there are

sum of terms-2237

number of terms-28

Median- 81

order the numbers from least to greatest

cross off the front number and back number until you are left with a middle

What's 2\5 =12/n solving proportions

gogolik [260]

Cross multiply: 2 * n = 5 * 12

Simplifying 2 * n = 5 * 12

Multiply 5 * 12 2n = 60

Solving 2n = 60

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Divide each side by '2'. n = 30

Simplifying n = 30
