What is 2/7 minus 4/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/7
Fraction B: 4/5

What to be found?
2/7-4/5 = ?
Find what's the difference between 2/7 and 4/5.

step 2 Compare the denominators of fractions 2/7 and 4/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/7 and 4/5 are not equal, it is said to be unlike fractions subtraction.

=10/35-28/35

step 6 Take the common values out and rewrite the above expression like the below:
=1/35 x (10/1-28/1)
=1/35 x (10 - 28)

step 7Simplify the above expression further:
=1/35 x -18
=-18/35
2/7-4/5=-18/35
