The LCM of 5 and 10 is 10.

step 4 Write the fractions 18/5 and 17/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 18/5 + 17/10
= [(18 x 10)/(5 x 10)] + [(17 x 10)/(10 x 10)]

step 5 Simplify the expression to have common denominator:
= 36/10 + 17/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (36/1 + 17/1)
= 1/10 x (36 + 17)

step 7Simplify the above expression further:
= 1/10 x 53
= 53/10
18/5 + 17/10 = 53/10
