To solve this, we first need to find a common denominator for all fractions involved.
The common denominator for 1/20, 1/4, 1/25, and 4/5 is 100.
Now, we convert each fraction to have a denominator of 100:
1/20 = 5/101/4 = 25/101/25 = 4/103 4/5 = 19/5 = 380/100
Now the equation becomes:
(5/100 - 25/100) /25 = (4/100 - 380/100) = -376/100
Simplifying the result, we get -376/100 = -94/25
Therefore, the answer is -94/25 or -3 19/25.
