step 4 Write the fractions 7/9 and 3/11 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/9+3/11
=(7 x 99)/(9 x 99)+(3 x 99)/(11 x 99)
step 5 Simplify the expression to have common denominator:
=77/99+27/99
step 6 Take the common values out and rewrite the above expression like the below:
=1/99 x (77/1+27/1)
=1/99 x (77 + 27)
step 7Simplify the above expression further:
=1/99 x 104
=104/99
7/9+3/11=104/99
