Answer:

?  = 22y^2

Step-by-step explanation:

Ask yourself, what times 20y will get me 40y^3?

The answer to this would be 2y^2.

When you multiply something to the denominator, you also have to do so to the numerator. Therefore, you are required to multiply 2y^2 to the 11 to get your '?' value.

11 x 2y^2 = 22y^2
