The LCM of 6 and 17 is 102.

step 4 Write the fractions 5/6 and 15/17 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/6 - 15/17
= [(5 x 102)/(6 x 102)] - [(15 x 102)/(17 x 102)]

step 5 Simplify the expression to have common denominator:
= 85/102 - 90/102

step 6 Take the common values out and rewrite the above expression like the below:
= 1/102 x (85/1 - 90/1)
= 1/102 x (85 - 90)

step 7Simplify the above expression further:
= 1/102 x -5
= -5/102
5/6 - 15/17 = -5/102

Hence,
