Let x=the number
Then 1/x= the reciprocal of the number
x+1/x=13/6 multiply each term by 6x
6x^2+6=13x subtract 13x from each side
6x^2-13x+6=0------------------quadratic in standard form. Solve using the quadratic formula:

and

This tells us that the number can either be 2/3 or 3/2
CK
2/3+3/2=13/6
4/6+9/6=13/6
13/6=13/6
