Answer:
a=b², a=2b, a=b/2. There is one more equation, find it on your own
Step-by-step explanation:
To solve such problems, you need to check, if b is in the numerator (an upper number in a fraction) or in the denominator (a lower number in a fraction). Every number and variable can be written as fraction x/1, where x is a number or variable. So, if b is in a numerator, then a is directly proportional to b, if b is in a denominator, then a is not directly proportional to b.
Also, you can use such method: input in b numbers that increase (for example, 1, then 2.). If a became bigger when b became bigger, then a is directly proportional to b.
