Solve the proportion.

5/6 = 10/x÷1

x = ?

Given expression:

                      =

Find x;

    To find x, let us first cross multiply;

       5 x (X /1)  = 6 x 10

  We know that any number divided by 1 will give back that same number; so the value of the expression in the parentheses is x

        5 x X   = 60;

So, divide both sides by 5 to give the value of X;

       X  =   = 12

The value of X is 12
