8th grade math equation? 10 points

[From: ] [author: ] [Date: 12-11-06] [Hit: ]
.Look attheexponts and ask...........
5 x^4 y^3 divided by 25 x^3 y^5

thank you so much! :)

-
5 x^4 y^3
-------------.........Now I am sure you can reduce the 5 over 25 to 1 over 5
25 x^3 y^5

When it comes to the letters here are two rules I teach my students:
Look at the exponts and ask...........
(1) Where are there MORE
(2) HOW many more

Where are there more x's............Top
How many more..............1
Put an x in the numerator

Where are there more y's............Bottom
How many more..............2
Put an y² in the denomenator

x
-----..............ANSWER
5y²

Let me know how to get in touch if you do not fully understand.

5x^4y^3 / 25x^3y^5

Factor out (cancel) the common 5:

x^4y^3 / 5x^3y^5

Factor out (cancel) the common x^3:

xy^3 / 5y^5

Factor out (cancel) the common y^3:

x / 5y^2

-
5(x^4)(y^3)/25(x^3)(y^5)=(5/25)(x^4/x^3)…
