Can you make the screen shot a bit clearer? Which question are you working on?

3. anonymous

yeah

4. anonymous

The one with jamie

5. anonymous

Okay, i can help with this :)

6. anonymous

bye

so, Were looking for the number of baseball cards. First, we have to know out of how many jamie pulled out, what fraction of that was baseball cards. We can find this by adding how many baseball cards and football cards jamie recorded. Using this, what do you think the fraction would be?

8. anonymous

um would it be 6/60 *9/60?

9. anonymous

Well, we need to find how many of the ones she/he pulled out were baseball cards, so it would be 6/15. Jamie pulled out 15 cards, and 6 of those are baseball cards. Does this make sense?

10. anonymous

But werent there 60 cards how do we get 15?

11. anonymous

$\pi$

12. anonymous

Oh nevermind you added 6 and 9

13. anonymous

Yes. so, now we have 6/15 because we only know how many baseball cards were in the amount jamie pulled out.

14. anonymous

Yes

15. anonymous

So, we need to figure out how many baseball cards are in the full stack. What times 15 equals 60? (Were basically doing the opposite of simplifying, were increasing it to make 15 have the same denominator as 60 :) )

16. anonymous

$\pi$

17. anonymous

4

18. anonymous

Exactly! Great job! Now, what you do to the bottom you have to do to the top. So, 6 x 4 equals?

19. anonymous

24

20. anonymous

Yep! So, our new fraction is 24/60. So, in the 60 cards that jamie has, 24 are baseball cards! Great job @nerd_3.14 !!

21. anonymous

So then whats the answer to the prroblem?

22. anonymous

23. anonymous
