2. Cross multiplication method.

(13/3) + (15/4) using LCM Method:
What is 13/3 plus 15/4 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/3
Fraction B: 15/4

What to be found?
(13/3) + (15/4) = ?
Find what's the sum of 13/3 and 15/4.

step 2 Compare the denominators of fractions 13/3 and 15/4 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 13/3 and 15/4 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 13/3 and 15/4:
The LCM of 3 and 4 is 12.

step 4 Write the fractions 13/3 and 15/4 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/3 + 15/4
= [(13 x 12)/(3 x 12)] + [(15 x 12)/(4 x 12)]

step 5 Simplify the expression to have common denominator:
= 52/12 + 45/12

step 6 Take the common values out and rewrite the above expression like the below:
= 1/12 x (52/1 + 45/1)
= 1/12 x (52 + 45)

step 7Simplify the above expression further:
= 1/12 x 97
= 97/12
13/3 + 15/4 = 97/12

Hence,
13/3 plus 15/4 as a fraction is 97/12.
