The answer to 5,22 as a fraction is 5/22
No, each does not mean to multiply, but it also depends on the question
So since the constant is the same we could divide them. If you know when you divide powers of 10 you subtract so it would be 5.34/5.34 which is 1 and 10^5- 10^-2. 5 - (-2). Which is 10^7 so it would be 1*10^7
