step 4 Write the fractions 13/6 and 15/14 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/6 + 15/14
= [(13 x 42)/(6 x 42)] + [(15 x 42)/(14 x 42)]

step 5 Simplify the expression to have common denominator:
= 91/42 + 45/42

step 6 Take the common values out and rewrite the above expression like the below:
= 1/42 x (91/1 + 45/1)
= 1/42 x (91 + 45)

step 7Simplify the above expression further:
= 1/42 x 136
= 136/42
= 68/21
