The LCM of 5 and 13 is 65.

step 4 Write the fractions 8/5 and 9/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 8/5 - 9/13
= [(8 x 65)/(5 x 65)] - [(9 x 65)/(13 x 65)]

step 5 Simplify the expression to have common denominator:
= 104/65 - 45/65

step 6 Take the common values out and rewrite the above expression like the below:
= 1/65 x (104/1 - 45/1)
= 1/65 x (104 - 45)

step 7Simplify the above expression further:
= 1/65 x 59
= 59/65
8/5 - 9/13 = 59/65
