What is 1/2 minus 1/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/7

What to be found?
1/2-1/7 = ?
Find what's the difference between 1/2 and 1/7.

step 2 Compare the denominators of fractions 1/2 and 1/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 1/7 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 1/7:
The LCM of 2 and 7 is 14.

step 4 Write the fractions 1/2 and 1/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-1/7
=(1 x 14)/(2 x 14)-(1 x 14)/(7 x 14)

step 5 Simplify the expression to have common denominator:
=7/14-2/14

step 6 Take the common values out and rewrite the above expression like the below:
=1/14 x (7/1-2/1)
=1/14 x (7 - 2)

step 7Simplify the above expression further:
=1/14 x 5
=5/14
1/2-1/7=5/14

Hence,
1/2 minus 1/7 equals to 5/14 in fraction.

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/7

What to be found?
1/2-1/7 = ?
Find what's the difference between 1/2 and 1/7.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 7), 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 7) and rewrite the equation as like the below:
= (1 x 7) - (1 x 2)/(2 x 7)

step 3 Simplify and rewrite the fraction:
= (7 - 2)/14
1/2-1/7 = 5/14
Hence,
1/2 minus 1/7 = 5/14
