2. Cross multiplication method.

(3/4) - (3/19) using LCM Method:
What is 3/4 minus 3/19 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/4
Fraction B: 3/19

What to be found?
(3/4) - (3/19) = ?
Find what's the difference between 3/4 and 3/19.

step 2 Compare the denominators of fractions 3/4 and 3/19 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/4 and 3/19 are not equal, it is said to be unlike fractions subtraction.

step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 3/4 and 3/19:
The LCM of 4 and 19 is 76.

step 4 Write the fractions 3/4 and 3/19 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 3/4 - 3/19
= [(3 x 76)/(4 x 76)] - [(3 x 76)/(19 x 76)]

step 5 Simplify the expression to have common denominator:
= 57/76 - 12/76

step 6 Take the common values out and rewrite the above expression like the below:
= 1/76 x (57/1 - 12/1)
= 1/76 x (57 - 12)

step 7Simplify the above expression further:
= 1/76 x 45
= 45/76
3/4 - 3/19 = 45/76

Hence,
3/4 minus 3/19 as a fraction is 45/76.
