(17/8) - (13/6) using LCM Method:
What is 17/8 minus 13/6 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 17/8
Fraction B: 13/6

What to be found?
(17/8) - (13/6) = ?
Find what's the difference between 17/8 and 13/6.

step 2 Compare the denominators of fractions 17/8 and 13/6 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 17/8 and 13/6 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 17/8 and 13/6:
The LCM of 8 and 6 is 24.

step 4 Write the fractions 17/8 and 13/6 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 17/8 - 13/6
= [(17 x 24)/(8 x 24)] - [(13 x 24)/(6 x 24)]

step 5 Simplify the expression to have common denominator:
= 51/24 - 52/24

step 6 Take the common values out and rewrite the above expression like the below:
= 1/24 x (51/1 - 52/1)
= 1/24 x (51 - 52)

step 7Simplify the above expression further:
= 1/24 x -1
= -1/24
17/8 - 13/6 = -1/24

Hence,
17/8 minus 13/6 as a fraction is -1/24.
