step 4 Write the fractions 12/5 and 5/14 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 12/5 - 5/14
= [(12 x 70)/(5 x 70)] - [(5 x 70)/(14 x 70)]

step 5 Simplify the expression to have common denominator:
= 168/70 - 25/70

step 6 Take the common values out and rewrite the above expression like the below:
= 1/70 x (168/1 - 25/1)
= 1/70 x (168 - 25)

step 7Simplify the above expression further:
= 1/70 x 143
= 143/70
12/5 - 5/14 = 143/70
