2. Cross multiplication method.

(13/1) + (5/7) using LCM Method:
What is 13/1 plus 5/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/1
Fraction B: 5/7

What to be found?
(13/1) + (5/7) = ?
Find what's the sum of 13/1 and 5/7.

step 2 Compare the denominators of fractions 13/1 and 5/7 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 13/1 and 5/7 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 13/1 and 5/7:
The LCM of 1 and 7 is 7.

step 4 Write the fractions 13/1 and 5/7 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/1 + 5/7
= [(13 x 7)/(1 x 7)] + [(5 x 7)/(7 x 7)]

step 5 Simplify the expression to have common denominator:
= 91/7 + 5/7

step 6 Take the common values out and rewrite the above expression like the below:
= 1/7 x (91/1 + 5/1)
= 1/7 x (91 + 5)

step 7Simplify the above expression further:
= 1/7 x 96
= 96/7
13/1 + 5/7 = 96/7

Hence,
13/1 plus 5/7 as a fraction is 96/7.
