(8/3) - (7/13) using LCM Method:
What is 8/3 minus 7/13 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/3
Fraction B: 7/13

What to be found?
(8/3) - (7/13) = ?
Find what's the difference between 8/3 and 7/13.

step 2 Compare the denominators of fractions 8/3 and 7/13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 8/3 and 7/13 are not equal, it is said to be unlike fractions subtraction.

step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 8/3 and 7/13:
The LCM of 3 and 13 is 39.

step 4 Write the fractions 8/3 and 7/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 8/3 - 7/13
= [(8 x 39)/(3 x 39)] - [(7 x 39)/(13 x 39)]

step 5 Simplify the expression to have common denominator:
= 104/39 - 21/39

step 6 Take the common values out and rewrite the above expression like the below:
= 1/39 x (104/1 - 21/1)
= 1/39 x (104 - 21)

step 7Simplify the above expression further:
= 1/39 x 83
= 83/39
8/3 - 7/13 = 83/39

Hence,
