For the first:

-x3y3
____

x45y

you can cancel out x and y on the bottom and top, because you're essentially dividing x by x and y by y, which are equal to one. You're left with:

-9
___

45

Which can be simplified to:

-1
___

5

For the second, call the first number "x" and the second "y".

The square of the first number is equal to x^2, and the second number to the fourth power is equal to y^4, obviously, so when multiplied together, they equal:

x^2 y^4

Just rewrite them in the correct mathematical form, obviously.

Simplifying algebraic fractions isn't that hard, you just need to understand the concepts behind what you're doing!
