Could someone please explain to me how to do false position?
For example, "a quantity; its half and its third are added to it. It becomes 10. What is the quantity?"
The algebraic way:
we want 12, so 12/11/3=36/11
Does anyone see where I went wrong? It should be 60/11, not 72/11. Does anyone know of an easy way of choosing the x value?
Thank you very much

Right ill try this one...
I think you're supposed to pick x so that the fractions go.
In this case try x=6.
You get 6 + 3 + 2 = 11 which is not the right answer.
But if we multiply 11 by 10/11 we get the right answer so multiply 6 by 10/11 and we do indeed get 60/11 as you said.
Following your way... Pick x=2.
Then you get 2 + 1 + 2/3 = 11/3 which is not the right answer but if we multiply it by 10*(3/11) we get the right answer so again multiply your x value by this to get 2*10*(3/11) to get 60/11 as required.
