step 4 Write the fractions 8/5 and 17/16 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 8/5 + 17/16
= [(8 x 80)/(5 x 80)] + [(17 x 80)/(16 x 80)]

step 5 Simplify the expression to have common denominator:
= 128/80 + 85/80

step 6 Take the common values out and rewrite the above expression like the below:
= 1/80 x (128/1 + 85/1)
= 1/80 x (128 + 85)

step 7Simplify the above expression further:
= 1/80 x 213
= 213/80
8/5 + 17/16 = 213/80
