Pharmacy Tech Math - Alligation tutorial
Alligation math is a little known short-cut used by pharmacy techs and pharmacy students. It's also known popularly in pharmacy tech school as tic-tac-toe math.
Here's the next steps in how to work an alligation:
( Cont'd from previous page )
So, now the amounts of the differences you found become the "Parts" of the % directly across the grid from it.
→ Parts of the 3%
→ Parts of the 1%
Now, take a look back at the question and look for the total volume needed.
Do the Math:
Now, you've divided the final solution volume into "Parts".
In this case, there's 125mL per part.
Now, go back up to the "parts" and write the volume per part.
The question asked how much 3% to use. So, that's :1 part X 125mL =
125mL of the 3%
Here's what your paper should look like when done
