= 12/13 + 11/16
= [(12 x 208)/(13 x 208)] + [(11 x 208)/(16 x 208)]

step 5 Simplify the expression to have common denominator:
= 192/208 + 143/208

step 6 Take the common values out and rewrite the above expression like the below:
= 1/208 x (192/1 + 143/1)
= 1/208 x (192 + 143)

step 7Simplify the above expression further:
= 1/208 x 335
= 335/208
12/13 + 11/16 = 335/208
