= [(15 x 63)/(7 x 63)] + [(14 x 63)/(9 x 63)]

step 5 Simplify the expression to have common denominator:
= 135/63 + 98/63

step 6 Take the common values out and rewrite the above expression like the below:
= 1/63 x (135/1 + 98/1)
= 1/63 x (135 + 98)

step 7Simplify the above expression further:
= 1/63 x 233
= 233/63
15/7 + 14/9 = 233/63
