The LCM of 4 and 14 is 28.

step 4 Write the fractions 9/4 and 9/14 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/4 + 9/14
= [(9 x 28)/(4 x 28)] + [(9 x 28)/(14 x 28)]

step 5 Simplify the expression to have common denominator:
= 63/28 + 18/28

step 6 Take the common values out and rewrite the above expression like the below:
= 1/28 x (63/1 + 18/1)
= 1/28 x (63 + 18)

step 7Simplify the above expression further:
= 1/28 x 81
= 81/28
9/4 + 9/14 = 81/28
