lubna saqer: thank u very much,, I have a question though.. do we always put the lowest
concentration up ? and what about this question that's not working with me
when I double check.. (a pharmacist receives a 4 oz of 10% solution using
a 25% and 5% solution)!
Tara B: This was very clear and helpful!
Lisa Waite: My professor in pharmacy school didn't explain this near as well as you
just did and it's been a bit like voodoo. Thanks for laying it out clearly
and explaining everything along the way, it makes total sense now!
Maria Garza: nice and easy ty

Samantha Schmidt: Thank you so much for posting this video!! It helped a lot!!
Upasna Patel: good job it is very nice.
Kristin Almajed: awesome video!!!
Zionsge: Thank you so much for this help! I had always gotten "eaten" by the
Alligation "alligator!" as my instructor so colorfully put it! Keep up the
good work, I will continue to pass on the info as you put it out!
Molan Labe: best explanation I've come across. Thank you!
NappingNappers: Wow it's called alligation! Nice work! I just do it lol
siral000: Well put overall, in the middle a little wordy, but good. I always
immediately start feeling my mind drift when someone is explaining
something to me and because they are so familiar with it, complicate it by
adding extra info like you could do this, or you could do that, some do
this, but I skip some steps and just do the other thing. Just spell out the
specific steps I need to know to get where I need to be. I'll pick up the
superfluous stuff later as I gain familiarity with it too.
victormania2008: i didn't really like this one
Rokeisha Roker: thank u for the video this was so helpful to me. I thought I was never
going to get it the way I was taught but in one view of this video it
became crystal clear to me. about to take my ptcb exam.
PaisleyFrizz: Thank you.
Robert Nahoopii: No, it really does not matter which number is on the bottom or top. When
you cross subtract your answer needs to be displayed as a positive value
(regardless if it is negative or not). You add these values to get your
total parts and then divide your value by the total parts to get your
relative percentage of parts for each ingredient. All of this can be done
and the answer this the same if you switch the two ingredients in their top
and bottom position.
russell navas: blew my mind how straight forward this is!
Robert Nahoopii: It was just an example. In this case, you have 1% hydrocortisone and 5%
hydrocortisone, but the doctor wants the patient to have 4% (which is not
commercially available). You buy the 1% and 5%.
Pwilliams8525: I really am happy that I found your youtube video everybody else on youtube
that has a alligation video doesn't know how to get straight to the point
and make the alligations alittle bite easier to understand.
Loveth Orajiato: Thankz, u made it soooooooooooo ezy
Anasherri: Like the 1% and 5% is the smaller number always on top in anygiven
problem.Is it always going to be like that?and what about the amounts after
cross subtract bigger always on bottom and smaller amount on top? Will that
always be the status in any given problem also?
Rocio Ferguson: Thanks it was so easy to understand !!!!
ColleenLoveWiley: Love it! Simply and to the point... Thank you.
Alyssa Antonetti: u r so awesome and i cannot even begin to thank you enough for explaining
ur version on how to do alligation math u defly made it so easy now im more
confident to take my test tomorrow!!!:) dont stop the videos someone always
sphetsalod: sooooooo easy!!!!!
Cosette Sales: i find this very helpful..wat is your site we can go to again?
da2nd2nn: thanks for uploading this. It made allegation really simple and i only had
to look at it once before testing my own examples
robnaho: Nice question. I will create a video about your exact question. For now,
you simply divide the volume you know by the percentage (in this case, 25
mL/0.75). This will give you your total volume, or 33.3 mL. You already
know how to find your final volume per ingredient when you have total
volume. You would now multiply 0.25 (the percentage of 90%) by 33.3 mL to
get 8.3 mL. So, 25 mL of 10% and 8.3 mL of 90% gives you 33.3 mL of 30%.
Akihiro Ito: How do u get 1% and5%. Which means is in the store ?
Allison R: This seemed more like alligation alternate not medial
Destiny Burroughs: Easy
kate J: thanks so much, that makes so much sense to me now.
Blog Dir: Building the website was not the hard part, but monetizing it was a whole new story. Thanks for the guidance about adsense. I am finally getting some money for my business directory. This is good for both business owners and customers. Keep building quality site and everyone wins.
