What is 2/5 minus 3/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 3/10

What to be found?
2/5-3/10 = ?
Find what's the difference between 2/5 and 3/10.

step 2 Compare the denominators of fractions 2/5 and 3/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/5 and 3/10 are not equal, it is said to be unlike fractions subtraction.

The LCM of 5 and 10 is 10.

step 4 Write the fractions 2/5 and 3/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=2/5-3/10
=(2 x 10)/(5 x 10)-(3 x 10)/(10 x 10)

step 5 Simplify the expression to have common denominator:
=4/10-3/10

step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (4/1-3/1)
=1/10 x (4 - 3)

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

Hence,
2/5 minus 3/10 equals to 1/10 in fraction.
