The LCM of 2 and 18 is 18.

step 4 Write the fractions 7/2 and 13/18 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/2 + 13/18
= [(7 x 18)/(2 x 18)] + [(13 x 18)/(18 x 18)]

step 5 Simplify the expression to have common denominator:
= 63/18 + 13/18

step 6 Take the common values out and rewrite the above expression like the below:
= 1/18 x (63/1 + 13/1)
= 1/18 x (63 + 13)

step 7Simplify the above expression further:
= 1/18 x 76
= 76/18
= 38/9
