The LCM of 7 and 12 is 84.

step 4 Write the fractions 13/7 and 13/12 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/7 + 13/12
= [(13 x 84)/(7 x 84)] + [(13 x 84)/(12 x 84)]

step 5 Simplify the expression to have common denominator:
= 156/84 + 91/84

step 6 Take the common values out and rewrite the above expression like the below:
= 1/84 x (156/1 + 91/1)
= 1/84 x (156 + 91)

step 7Simplify the above expression further:
= 1/84 x 247
= 247/84
13/7 + 13/12 = 247/84

Hence,
