The LCM of 5 and 4 is 20.

step 4 Write the fractions 17/5 and 9/4 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 17/5 + 9/4
= [(17 x 20)/(5 x 20)] + [(9 x 20)/(4 x 20)]

step 5 Simplify the expression to have common denominator:
= 68/20 + 45/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (68/1 + 45/1)
= 1/20 x (68 + 45)

step 7Simplify the above expression further:
= 1/20 x 113
= 113/20
17/5 + 9/4 = 113/20

Hence,
