Why exactly did u multiply 3/4 to 8? could you clarity that ? Question number 31
I found that I could have 8 complete pieces of 3/4 yards that I can cut from a length of 6.5 yards. By multiplying 8 by 3/4 yards, this gives me the total length of 8 pieces that I would need to make the bows. This resulting length of 6 yards can then be subtracted from 6.5 yards to yield the portion of the ribbon that will not be used. I hope this makes sense.

I can’t find the video answer for Math 24 for form B05. I just paid membership to find this answer explanation and it’s not here.
The video explanation to Question 24 is in the playlist. You just have to scroll backward.
Hi, where exactly can I download the test pdf for the Dec 2018 test? So I can take the test and follow along with the videos?
Someone posted it here.

I swear 36 is wrong. H cannot be possible for that question. It has to be J. Someone please help me understand what’s wrong with either the test or my thought process
If you want 1 ounce of element X, you need 10 ounces of compound Y because 10$\%$ of compound Y is element X. 16 ounces of compound Y will cost $\$$2.40, so 10 ounces of compound Y will cost 10/16 * $\$$2.40 = $\$$1.50. The premise of the question is that you don’t have to purchase compound Y in whole pound quantities. You can purchase exactly the 10 ounces that you need in order to get 1 ounce of element X.
I’m not sure why it formatted so strangely. Sorry about that.
Thanks for answering this. I have fixed the editing because of the math symbols.
One doesn’t have to buy an entire pound, you can purchase any amount similar to buying say flour or sugar.
