i will post my answer choices!

Start like the last one. Multiply the numerators together, and multiply the denominators together. What do you get?

5. mathstudent55

Fill in the numerator and denominator below. |dw:1433102924872:dw|

Copy my last figure, and fill in the bottom fraction. Then we'll continue.

10. mathstudent55

No. Don't combine the numbers, just fill in they way they are.

what do you mean?

13. mathstudent55

Remember, teh numerators are being multiplied, and 5 * 4 = 20, not 5 + 4 = 9.

14. anonymous

oh ok now i understand!!

15. mathstudent55

Ok. Let me move it to a cleaner figure.

16. anonymous

ok

17. mathstudent55

We have this so far. We multiplied the two original numerators together, and the two original denominators together. |dw:1433103252101:dw|

18. anonymous

okay!

19. mathstudent55

Now we work on the new numerator and the new denominator.

20. mathstudent55

|dw:1433103370155:dw|

21. mathstudent55

We multiply 5 * 4 and get 20

23. anonymous

ok

24. mathstudent55

Now we need to simplify. To simplify, we need to cancel out common factors in the numerator and denominator.

27. mathstudent55

I separated the factors out to show what can be canceled.
