step 4 Write the fractions 9/7 and 5/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/7 - 5/13
= [(9 x 91)/(7 x 91)] - [(5 x 91)/(13 x 91)]

step 5 Simplify the expression to have common denominator:
= 117/91 - 35/91

step 6 Take the common values out and rewrite the above expression like the below:
= 1/91 x (117/1 - 35/1)
= 1/91 x (117 - 35)

step 7Simplify the above expression further:
= 1/91 x 82
= 82/91
9/7 - 5/13 = 82/91
