1/2-8/19 using LCM Method:
What is 1/2 minus 8/19 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 8/19
What to be found?
1/2-8/19 = ?
Find what's the difference between 1/2 and 8/19.
step 2 Compare the denominators of fractions 1/2 and 8/19 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 8/19 are not equal, it is said to be unlike fractions subtraction.

The LCM of 2 and 19 is 38.
step 4 Write the fractions 1/2 and 8/19 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-8/19
=(1 x 38)/(2 x 38)-(8 x 38)/(19 x 38)
step 5 Simplify the expression to have common denominator:
=19/38-16/38
step 6 Take the common values out and rewrite the above expression like the below:
=1/38 x (19/1-16/1)
=1/38 x (19 - 16)
step 7Simplify the above expression further:
=1/38 x 3
=3/38
1/2-8/19=3/38
Hence,
