What is 3/8 minus 1/12 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/8
Fraction B: 1/12
What to be found?
3/8-1/12 = ?
Find what's the difference between 3/8 and 1/12.
step 2 Compare the denominators of fractions 3/8 and 1/12 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/8 and 1/12 are not equal, it is said to be unlike fractions subtraction.

The LCM of 8 and 12 is 24.
step 4 Write the fractions 3/8 and 1/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/8-1/12
=(3 x 24)/(8 x 24)-(1 x 24)/(12 x 24)
step 5 Simplify the expression to have common denominator:
=9/24-2/24
step 6 Take the common values out and rewrite the above expression like the below:
=1/24 x (9/1-2/1)
=1/24 x (9 - 2)
step 7Simplify the above expression further:
=1/24 x 7
=7/24
3/8-1/12=7/24
