Writing some equations out might help!
1) You know that a is 4/5 of b. This can be written as:

.
To find what b is equal to, multiply both sides by 5/4:

.
A is 5/4 B.
2) You know that a is 1/5 smaller than b. This can be written as:

.
To find b, just add 1/5 to both sides:

.
B is 1/5 bigger than a.
