What is 7/10 minus 2/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/10
Fraction B: 2/5

What to be found?
7/10-2/5 = ?
Find what's the difference between 7/10 and 2/5.

step 2 Compare the denominators of fractions 7/10 and 2/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/10 and 2/5 are not equal, it is said to be unlike fractions subtraction.

The LCM of 10 and 5 is 10.

step 4 Write the fractions 7/10 and 2/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/10-2/5
=(7 x 10)/(10 x 10)-(2 x 10)/(5 x 10)

step 5 Simplify the expression to have common denominator:
=7/10-4/10

step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (7/1-4/1)
=1/10 x (7 - 4)

step 7Simplify the above expression further:
=1/10 x 3
=3/10
7/10-2/5=3/10

Hence,
7/10 minus 2/5 equals to 3/10 in fraction.
