= 3/7 + 5/14
= [(3 x 14)/(7 x 14)] + [(5 x 14)/(14 x 14)]

step 5 Simplify the expression to have common denominator:
= 6/14 + 5/14

step 6 Take the common values out and rewrite the above expression like the below:
= 1/14 x (6/1 + 5/1)
= 1/14 x (6 + 5)

step 7Simplify the above expression further:
= 1/14 x 11
= 11/14
