The LCM of 9 and 14 is 126.
step 4 Write the fractions 7/9 and 4/14 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/9+4/14
=(7 x 126)/(9 x 126)+(4 x 126)/(14 x 126)
step 5 Simplify the expression to have common denominator:
=98/126+36/126
step 6 Take the common values out and rewrite the above expression like the below:
=1/126 x (98/1+36/1)
=1/126 x (98 + 36)
step 7Simplify the above expression further:
=1/126 x 134
= 134/126
=67/63
7/9+4/14=67/63
