= [(13 x 18)/(2 x 18)] + [(7 x 18)/(18 x 18)]

step 5 Simplify the expression to have common denominator:
= 117/18 + 7/18

step 6 Take the common values out and rewrite the above expression like the below:
= 1/18 x (117/1 + 7/1)
= 1/18 x (117 + 7)

step 7Simplify the above expression further:
= 1/18 x 124
= 124/18
= 62/9
