= [(17 x 68)/(4 x 68)] - [(9 x 68)/(17 x 68)]

step 5 Simplify the expression to have common denominator:
= 289/68 - 36/68

step 6 Take the common values out and rewrite the above expression like the below:
= 1/68 x (289/1 - 36/1)
= 1/68 x (289 - 36)

step 7Simplify the above expression further:
= 1/68 x 253
= 253/68
17/4 - 9/17 = 253/68
