(11/3) + (17/8) using LCM Method:
What is 11/3 plus 17/8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 11/3
Fraction B: 17/8

What to be found?
(11/3) + (17/8) = ?
Find what's the sum of 11/3 and 17/8.

step 2 Compare the denominators of fractions 11/3 and 17/8 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 11/3 and 17/8 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 11/3 and 17/8:
The LCM of 3 and 8 is 24.

step 4 Write the fractions 11/3 and 17/8 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 11/3 + 17/8
= [(11 x 24)/(3 x 24)] + [(17 x 24)/(8 x 24)]

step 5 Simplify the expression to have common denominator:
= 88/24 + 51/24

step 6 Take the common values out and rewrite the above expression like the below:
= 1/24 x (88/1 + 51/1)
= 1/24 x (88 + 51)

step 7Simplify the above expression further:
= 1/24 x 139
= 139/24
11/3 + 17/8 = 139/24

Hence,
11/3 plus 17/8 as a fraction is 139/24.
