The LCM of 4 and 12 is 12.

step 4 Write the fractions 15/4 and 17/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/4 - 17/12
= [(15 x 12)/(4 x 12)] - [(17 x 12)/(12 x 12)]

step 5 Simplify the expression to have common denominator:
= 45/12 - 17/12

step 6 Take the common values out and rewrite the above expression like the below:
= 1/12 x (45/1 - 17/1)
= 1/12 x (45 - 17)

step 7Simplify the above expression further:
= 1/12 x 28
= 28/12
= 7/3
15/4 - 17/12 = 7/3
