What is 1/2 minus 3/8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 3/8

What to be found?
1/2-3/8 = ?
Find what's the difference between 1/2 and 3/8.

step 2 Compare the denominators of fractions 1/2 and 3/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 3/8 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 3/8:
The LCM of 2 and 8 is 8.

step 4 Write the fractions 1/2 and 3/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-3/8
=(1 x 8)/(2 x 8)-(3 x 8)/(8 x 8)

step 5 Simplify the expression to have common denominator:
=4/8-3/8

step 6 Take the common values out and rewrite the above expression like the below:
=1/8 x (4/1-3/1)
=1/8 x (4 - 3)

step 7Simplify the above expression further:
=1/8 x 1
=1/8
1/2-3/8=1/8

Hence,
1/2 minus 3/8 equals to 1/8 in fraction.

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 3/8

What to be found?
1/2-3/8 = ?
Find what's the difference between 1/2 and 3/8.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 8), find the product of numerator of Fraction B and denominator of Fraction A (3 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 8) and rewrite the equation as like the below:
= (1 x 8) - (3 x 2)/(2 x 8)

step 3 Simplify and rewrite the fraction:
= (8 - 6)/16
= 2/16
= 1/8
1/2-3/8 = 1/8
Hence,
1/2 minus 3/8 = 1/8
