can someone show work for 12/13 - 1/3 = ?

Find a common denominator (39), and multiply 12 by 3 and multiply 1 times 13. You should get (36/39)-(13/39). The rest is simple.

12/13 - 1/3 = ? ok see here : take LCM of 13 and 3 ( demominators ) that is 39 \[12/13-1/3\] \[12(3) - 1(13)/39\] \[36-13/39\] \[23/39\]
