Question

Find the mean proportion of the following :

`28/3` and `175/27`

Solution

Let x be the mean proportion 

`28/3 : "x" : : "x" : 175/27 `

`=> "x" xx "x" = 28/3 xx 175/27`

`=> "x"^2 = 4900/81`

`=> "x" = sqrt(4900/81)`

`=> "x" = 70/9`

The mean proportion is `70/9`

  Is there an error in this question or solution?
