What is 6/8 minus 1/2 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 6/8
Fraction B: 1/2
What to be found?
6/8-1/2 = ?
Find what's the difference between 6/8 and 1/2.
step 2 Compare the denominators of fractions 6/8 and 1/2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 6/8 and 1/2 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 6/8 and 1/2:
The LCM of 8 and 2 is 8.
step 4 Write the fractions 6/8 and 1/2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=6/8-1/2
=(6 x 8)/(8 x 8)-(1 x 8)/(2 x 8)
step 5 Simplify the expression to have common denominator:
=6/8-4/8
step 6 Take the common values out and rewrite the above expression like the below:
=1/8 x (6/1-4/1)
=1/8 x (6 - 4)
step 7Simplify the above expression further:
=1/8 x 2
= 2/8
=1/4
6/8-1/2=1/4
Hence,
6/8 minus 1/2 equals to 1/4 in fraction.
