(7/2) + (9/13) using LCM Method:
What is 7/2 plus 9/13 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 9/13

What to be found?
(7/2) + (9/13) = ?
Find what's the sum of 7/2 and 9/13.

step 2 Compare the denominators of fractions 7/2 and 9/13 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/2 and 9/13 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 7/2 and 9/13:
The LCM of 2 and 13 is 26.

step 4 Write the fractions 7/2 and 9/13 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/2 + 9/13
= [(7 x 26)/(2 x 26)] + [(9 x 26)/(13 x 26)]

step 5 Simplify the expression to have common denominator:
= 91/26 + 18/26

step 6 Take the common values out and rewrite the above expression like the below:
= 1/26 x (91/1 + 18/1)
= 1/26 x (91 + 18)

step 7Simplify the above expression further:
= 1/26 x 109
= 109/26
7/2 + 9/13 = 109/26

Hence,
7/2 plus 9/13 as a fraction is 109/26.
