The LCM of 4 and 17 is 68.

step 4 Write the fractions 15/4 and 5/17 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/4 + 5/17
= [(15 x 68)/(4 x 68)] + [(5 x 68)/(17 x 68)]

step 5 Simplify the expression to have common denominator:
= 255/68 + 20/68

step 6 Take the common values out and rewrite the above expression like the below:
= 1/68 x (255/1 + 20/1)
= 1/68 x (255 + 20)

step 7Simplify the above expression further:
= 1/68 x 275
= 275/68
15/4 + 5/17 = 275/68

Hence,
