2. Cross multiplication method.

(5/4) + (15/16) using LCM Method:
What is 5/4 plus 15/16 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/4
Fraction B: 15/16

What to be found?
(5/4) + (15/16) = ?
Find what's the sum of 5/4 and 15/16.

step 2 Compare the denominators of fractions 5/4 and 15/16 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 5/4 and 15/16 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 5/4 and 15/16:
The LCM of 4 and 16 is 16.

step 4 Write the fractions 5/4 and 15/16 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/4 + 15/16
= [(5 x 16)/(4 x 16)] + [(15 x 16)/(16 x 16)]

step 5 Simplify the expression to have common denominator:
= 20/16 + 15/16

step 6 Take the common values out and rewrite the above expression like the below:
= 1/16 x (20/1 + 15/1)
= 1/16 x (20 + 15)

step 7Simplify the above expression further:
= 1/16 x 35
= 35/16
5/4 + 15/16 = 35/16

Hence,
5/4 plus 15/16 as a fraction is 35/16.
