2. Cross multiplication method.

(15/8) - (17/6) using LCM Method:
What is 15/8 minus 17/6 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/8
Fraction B: 17/6

What to be found?
(15/8) - (17/6) = ?
Find what's the difference between 15/8 and 17/6.

step 2 Compare the denominators of fractions 15/8 and 17/6 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 15/8 and 17/6 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 15/8 and 17/6:
The LCM of 8 and 6 is 24.

step 4 Write the fractions 15/8 and 17/6 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/8 - 17/6
= [(15 x 24)/(8 x 24)] - [(17 x 24)/(6 x 24)]

step 5 Simplify the expression to have common denominator:
= 45/24 - 68/24

step 6 Take the common values out and rewrite the above expression like the below:
= 1/24 x (45/1 - 68/1)
= 1/24 x (45 - 68)

step 7Simplify the above expression further:
= 1/24 x -23
= -23/24
15/8 - 17/6 = -23/24

Hence,
15/8 minus 17/6 as a fraction is -23/24.
