What is 8/10 minus 1/8 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/10
Fraction B: 1/8
What to be found?
8/10-1/8 = ?
Find what's the difference between 8/10 and 1/8.
step 2 Compare the denominators of fractions 8/10 and 1/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 8/10 and 1/8 are not equal, it is said to be unlike fractions subtraction.

step 4 Write the fractions 8/10 and 1/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=8/10-1/8
=(8 x 40)/(10 x 40)-(1 x 40)/(8 x 40)
step 5 Simplify the expression to have common denominator:
=32/40-5/40
step 6 Take the common values out and rewrite the above expression like the below:
=1/40 x (32/1-5/1)
=1/40 x (32 - 5)
step 7Simplify the above expression further:
=1/40 x 27
=27/40
8/10-1/8=27/40
