= [(15 x 20)/(2 x 20)] + [(13 x 20)/(20 x 20)]

step 5 Simplify the expression to have common denominator:
= 150/20 + 13/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (150/1 + 13/1)
= 1/20 x (150 + 13)

step 7Simplify the above expression further:
= 1/20 x 163
= 163/20
15/2 + 13/20 = 163/20
