Answer:
`\textsf{28 1/3}`

-------------------------------------------------------------------------------------------------------------

Given:
`\textsf{We are given 9 numbers}`

Find:
`\textsf{Determine the mean of the numbers}`

Solution: In order to determine the mean of the numbers the first step that we need to do is to add up all of the numbers. After adding up all of the numbers we divide it by the amount of numbers that were provided to us.

Add up the numbers

• 
  `\textsf{120 + 60 + 0 + 30 + 15 + 0 + 0 + 10 + 20}`

• 
  `\textsf{255}`

Divide it by the amount of numbers provided

• 
  `\textsf{255 / 9}`

• 
  `\textsf{((28 * 9) + 3) / 9}`

• 
  `\textsf{28 (3/9)}`

• 
  `\textsf{28 1/3}`

Therefore, the mean of the numbers provided is
`\textsf{28 1/3}`
