What is 4/5 minus 3/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/5
Fraction B: 3/10

What to be found?
4/5-3/10 = ?
Find what's the difference between 4/5 and 3/10.

step 2 Compare the denominators of fractions 4/5 and 3/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 4/5 and 3/10 are not equal, it is said to be unlike fractions subtraction.

=8/10-3/10

step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (8/1-3/1)
=1/10 x (8 - 3)

step 7Simplify the above expression further:
=1/10 x 5
= 5/10
=1/2
4/5-3/10=1/2

Hence,
