step 4 Write the fractions 7/4 and 9/19 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/4 - 9/19
= [(7 x 76)/(4 x 76)] - [(9 x 76)/(19 x 76)]

step 5 Simplify the expression to have common denominator:
= 133/76 - 36/76

step 6 Take the common values out and rewrite the above expression like the below:
= 1/76 x (133/1 - 36/1)
= 1/76 x (133 - 36)

step 7Simplify the above expression further:
= 1/76 x 97
= 97/76
7/4 - 9/19 = 97/76
