What is 7/10 minus 1/2 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/10
Fraction B: 1/2

What to be found?
7/10-1/2 = ?
Find what's the difference between 7/10 and 1/2.

step 2 Compare the denominators of fractions 7/10 and 1/2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/10 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 7/10 and 1/2:
The LCM of 10 and 2 is 10.

step 4 Write the fractions 7/10 and 1/2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/10-1/2
=(7 x 10)/(10 x 10)-(1 x 10)/(2 x 10)

step 5 Simplify the expression to have common denominator:
=7/10-5/10

step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (7/1-5/1)
=1/10 x (7 - 5)

step 7Simplify the above expression further:
=1/10 x 2
= 2/10
=1/5
7/10-1/2=1/5

Hence,
7/10 minus 1/2 equals to 1/5 in fraction.

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/10
Fraction B: 1/2

What to be found?
7/10-1/2 = ?
Find what's the difference between 7/10 and 1/2.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 2), find the product of numerator of Fraction B and denominator of Fraction A (1 x 10), and find the product of both denominators of Fraction A and Fraction B (10 x 2) and rewrite the equation as like the below:
= (7 x 2) - (1 x 10)/(10 x 2)

step 3 Simplify and rewrite the fraction:
= (14 - 10)/20
= 4/20
= 1/5
7/10-1/2 = 1/5
Hence,
7/10 minus 1/2 = 1/5
