2. Cross multiplication method.

(16/5) + (1/8) using LCM Method:
What is 16/5 plus 1/8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 16/5
Fraction B: 1/8

What to be found?
(16/5) + (1/8) = ?
Find what's the sum of 16/5 and 1/8.

step 2 Compare the denominators of fractions 16/5 and 1/8 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 16/5 and 1/8 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 16/5 and 1/8:
The LCM of 5 and 8 is 40.

step 4 Write the fractions 16/5 and 1/8 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 16/5 + 1/8
= [(16 x 40)/(5 x 40)] + [(1 x 40)/(8 x 40)]

step 5 Simplify the expression to have common denominator:
= 128/40 + 5/40

step 6 Take the common values out and rewrite the above expression like the below:
= 1/40 x (128/1 + 5/1)
= 1/40 x (128 + 5)

step 7Simplify the above expression further:
= 1/40 x 133
= 133/40
16/5 + 1/8 = 133/40

Hence,
16/5 plus 1/8 as a fraction is 133/40.
