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

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/4
What to be found?
1/2-1/4 = ?
Find what's the difference between 1/2 and 1/4.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 4), find the product of numerator of Fraction B and denominator of Fraction A (1 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 4) and rewrite the equation as like the below:
= (1 x 4) - (1 x 2)/(2 x 4)
step 3 Simplify and rewrite the fraction:
= (4 - 2)/8
= 2/8
= 1/4
1/2-1/4 = 1/4
Hence,
1/2 minus 1/4 = 1/4
