= [(13 x 91)/(7 x 91)] - [(5 x 91)/(13 x 91)]

step 5 Simplify the expression to have common denominator:
= 169/91 - 35/91

step 6 Take the common values out and rewrite the above expression like the below:
= 1/91 x (169/1 - 35/1)
= 1/91 x (169 - 35)

step 7Simplify the above expression further:
= 1/91 x 134
= 134/91
13/7 - 5/13 = 134/91
