The below workout with step by step calculation shows how to find the equivalent fraction between 9/1 and 7/9 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 9/1 plus 7/9 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(9/1) + (7/9) using LCM Method:
What is 9/1 plus 7/9 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/1
Fraction B: 7/9

What to be found?
(9/1) + (7/9) = ?
Find what's the sum of 9/1 and 7/9.

step 2 Compare the denominators of fractions 9/1 and 7/9 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 9/1 and 7/9 are not equal, it is said to be unlike fractions addition.

step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 9/1 and 7/9:
The LCM of 1 and 9 is 9.

step 4 Write the fractions 9/1 and 7/9 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/1 + 7/9
= [(9 x 9)/(1 x 9)] + [(7 x 9)/(9 x 9)]

step 5 Simplify the expression to have common denominator:
= 81/9 + 7/9

step 6 Take the common values out and rewrite the above expression like the below:
= 1/9 x (81/1 + 7/1)
= 1/9 x (81 + 7)

step 7Simplify the above expression further:
= 1/9 x 88
= 88/9
9/1 + 7/9 = 88/9

Hence,
9/1 plus 7/9 as a fraction is 88/9.
