= 13/11 + 11/20
= [(13 x 220)/(11 x 220)] + [(11 x 220)/(20 x 220)]

step 5 Simplify the expression to have common denominator:
= 260/220 + 121/220

step 6 Take the common values out and rewrite the above expression like the below:
= 1/220 x (260/1 + 121/1)
= 1/220 x (260 + 121)

step 7Simplify the above expression further:
= 1/220 x 381
= 381/220
