2. Cross multiplication method.

(15/1) + (13/9) using LCM Method:
What is 15/1 plus 13/9 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/1
Fraction B: 13/9

What to be found?
(15/1) + (13/9) = ?
Find what's the sum of 15/1 and 13/9.

step 2 Compare the denominators of fractions 15/1 and 13/9 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 15/1 and 13/9 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 15/1 and 13/9:
The LCM of 1 and 9 is 9.

step 4 Write the fractions 15/1 and 13/9 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/1 + 13/9
= [(15 x 9)/(1 x 9)] + [(13 x 9)/(9 x 9)]

step 5 Simplify the expression to have common denominator:
= 135/9 + 13/9

step 6 Take the common values out and rewrite the above expression like the below:
= 1/9 x (135/1 + 13/1)
= 1/9 x (135 + 13)

step 7Simplify the above expression further:
= 1/9 x 148
= 148/9
15/1 + 13/9 = 148/9

Hence,
15/1 plus 13/9 as a fraction is 148/9.
