step 4 Write the fractions 5/8 and 3/13 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/8 + 3/13
= [(5 x 104)/(8 x 104)] + [(3 x 104)/(13 x 104)]

step 5 Simplify the expression to have common denominator:
= 65/104 + 24/104

step 6 Take the common values out and rewrite the above expression like the below:
= 1/104 x (65/1 + 24/1)
= 1/104 x (65 + 24)

step 7Simplify the above expression further:
= 1/104 x 89
= 89/104
5/8 + 3/13 = 89/104
