Easy math. Start with 6mL of your 50/50 stuff (3mL each of PG and VG). Now add 4mL of VG.
So that gives me 10 ml of 30/70 pg/vg? Thanks so what would it be to get 40/60 pg/vg 0 nic using 30/70 pg vg 0 nic?
So the math is less easy here, but if you're starting with the 10mL of 30/70 you just made, you can add 3mL of PG and get pretty close to 40/60.
Or you can start over with 8mL of your 50/50 solution and add 2mL of VG.

Sorry didn't make myself clear. I am starting with premixed from vendor 70/30pg/vg and want to make it 40/60 pg/vg.
One last thing I hate to bother you but while I have you here how do I make 40/60 pg/vg out of 10/90 pg/vg.
Remember all that stuff in 4th grade math class about fractions? I guess we DID need to pay attention. Lol! If you have PG, VG and measuring equip, why not just make it from scratch. Cheaper and easier.
Coincidentally enough, if you mix equal parts of your 70/30 with your 10/90...guess what you get? Bingo: 40/60.
These are two different mixes though one which is Dr fog max vg 10/90 which I need to know how to get it to 40/60? Lol
I realize this will dilute the flavor bit I'm fine with that. I used my ejuice calculator and this is what I enteres
So I have entered in 0 nic at 10/90 for my base, then my target at 40/60 pg/vg. I then added 1 flavor which I inserted at 50% 10/90pg/vg which is the 0 nic ejuice (Dr Fog) I want a target of 40/60 pg/vg. So all said and done the results on the bottom of the ejuice calculator looks right to me. What do you think?
It's perfectly fine. Essentially, it tells you to mix 70/30 in equal measure with your 10/90 to make 40/60. Now where did I hear that before?
Lol I didn't doubt you but with a memory like mine and crappy with the fraction thing knowing how to do it on the ejuice calculator prevents you and others from getting annoyed with me asking questions or blocking me haha. Thanks for your help!!It's perfectly fine. Essentially, it tells you to mix 70/30 in equal measure with your 10/90 to make 40/60. Now where did I hear that before?

Lol if you live for this stuff I have one for ya to figure out.
I want to make 10 ml of this ejuice.
Purchased eliquid is 26/74 pg/vg 0 nic
I want it to be 30/70 pg/vg 0 nic
I want to mix it assuming 20 drops = 1ml
You have 1 "part" 26% PG liquid. How much (x) PG should you add so the resulting mix is 30% pg? In the end you will have 1+x parts liquid.
The amount of PG in your final mix will be "x" plus the amount of PG in your starting liquid (.26 parts). That will be "x + .26"
A: x + .26 = the PG you added plus the PG there was to begin with. This is the total amount (in "parts") of PG in the final mix.
B: 1 + x = total volume for final mix
C: .30 * (1 + x) = 30% of the final volume, or total amount of PG in the final mix.
Note that A and C are both equal to the "total amount of PG in the final mix." Since they are both equal to the same amount, we know that they are also equal to each other. When two things are equal to each other, they can be represented by an equation: .30(1+x) = x + .26
Now let's bust out our math skills:
.30(1+x) = x + .26
Expand parentheses:
.3 + .3x = x + .26
Subtract .26 from both sides:
.04 + .3x = x
Subtract .3x from both sides:
.04 = .7x
Divide both sides by .7:
.05714... = x
You should add about .057 parts, or 5.7% of the initial amount, of PG. Let's check our work. Say you have 10ml to start with:
10ml * .26 = 2.6ml PG in your starting liquid. 5.7% of 10ml is .57 ml. If you add .57 ml of PG you will have 10.57ml total volume, with 3.17ml of PG in it. 3.17 (the new amount of PG) divided by 10.57 (the new total volume) equals:
3.17/10.57 = 0.299905..., or very close to .3 (30%). The math checks out. Start with any amount of the 26/74, take 5.7% of that amount, and add that much PG. The result will be 30% PG.

That is Incredible!!! It makes complete sense. I suck at stuff like this bit when you break it all down and think about it, it makes sense. Thanks so much for taking the time to explain it out in detail to me.
Alternatively, for 10ml final volume:
3ml PG = 30% of 10ml
"x" added PG plus "10 - x" starting volume equals 10ml.
.26 times "10 - x" is the amount of PG you start with.
.26 times 10-x plus x will be the final amount of PG, which we want to equal 3ml. There's your equation:
.26(10-x) + x = 3
This one's a bit easier, since the x's are all on one side already. Again, we start by expanding the parentheses:
2.6 + .26x + x = 3
Subtract 2.6 from each side:
.26x + x = 3 - 2.6
Combine "like terms":
1.26x = .4
And finally, divide each side by 1.26:
x = .31746...
So you add "x" amount of PG (.32ml) to "10-x" amount of original liquid (9.68ml) and you have 10ml final volume. The amount of PG in the total is the .32ml that you added plus 26% of the 9.68 which is 2.5168. Add those together and you get 2.5168 + .32 = 2.8368. Not quite the 3ml we were looking for but if you can measure exactly .317460317460... and 9.68253968253... (both repeating to infinity) ml's then more power to ya!
3ml PG = 30% of 10ml
"x" added PG plus "10 - x" starting volume equals 10ml.
.26 times "10 - x" is the amount of PG you start with.
.26 times 10-x plus x will be the final amount of PG, which we want to equal 3ml. There's your equation:
.26(10-x) + x = 3
This one's a bit easier, since the x's are all on one side already. Again, we start by expanding the parentheses:
2.6 + .26x + x = 3
Subtract 2.6 from each side:
.26x + x = 3 - 2.6
Combine "like terms":
1.26x = .4
And finally, divide each side by 1.26:
x = .31746...
So you add "x" amount of PG (.32ml) to "10-x" amount of original liquid (9.68ml) and you have 10ml final volume. The amount of PG in the total is the .32ml that you added plus 26% of the 9.68 which is 2.5168. Add those together and you get 2.5168 + .32 = 2.8368.
