no, but 6 to 94 would be.
NO. If you mix them in equal parts, that would give you 35 volume. To get 15 volume, mix equal parts of 10 and 20 volume.
If you have vinegar with less acidity than 5 percent, then yes. For instance, if you somehow had 0 percent vinegar, mixing the two half-and-half would give you 5 percent. If you have 2.5 percent, mixing 1 part 2.5 percent with 2 parts 10 percent will give you 5 percent.
64.5 percent is equal to 0.645 in decimal form or 645 parts per thousand in fractional form.
by "ppm" I assume you mean "parts per million". 30 percent means 30 per 100, and 1,000,000 (a million) divided by 100 is equal to 10,000. This is the ration between ppm and percent. 30x10,000 is equal to 300,000, so 30 percent is equal to 300,000 ppm
The only way to make a 20 volume would be to mix equal parts of 30 and 10 volumes.
NO. If you mix them in equal parts, that would give you 35 volume. To get 15 volume, mix equal parts of 10 and 20 volume.
You need one part vinegar to four equal parts water.
the volume of its parts would be equal to the amount off butts an object gives off
If you have vinegar with less acidity than 5 percent, then yes. For instance, if you somehow had 0 percent vinegar, mixing the two half-and-half would give you 5 percent. If you have 2.5 percent, mixing 1 part 2.5 percent with 2 parts 10 percent will give you 5 percent.
70,000ppm
25 percent out of 100 is 0.25 * 100 = 25.
64.5 percent is equal to 0.645 in decimal form or 645 parts per thousand in fractional form.
Equal parts of 30 volume + 40 volume developers= 35 Volume Developer.

Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
The only way to make a 20 volume would be to mix equal parts of 30 and 10 volumes.
If you mix them in equal parts, you now have 25 volume developer.
