4 ounces. 2.5 is 1/8 of 20. So 1/8 of 32 ounces is how much you need. 32 divided by 8 is 4. You need 4 ounces.
420 gallons. Here's how to find it; If X = Gallons of 80% mix, 0.8*X + 0.1*70 = 0.7*(X+70) Which we can then solve, 0.8X + 7 = 0.7X + 49 0.1X = 42 X = 420
5 half gallons to 1 half gallon
It depends on the mixing ratio of gasoline / oil for the specific piece of equipment you will use the gas / oil mix. Most lawn equipment such as weed eaters and leaf blowers require a 32:1 mixture. Since 1 gallon of gasoline is 128 ounces, it is necessary to mix 128 ounces (or 1 US gallon) of gasoline to 4 ounces of 2 cycle oil to equal 32:1 ratio.

You can separate 6 ounces out of your 640 ounces (640 / 6) = 106 and 2/3 times. Lets take the 106 times first: With these, you can treat 106 gallons of water. Each time you do that, you wind up with 134 ounces of mixture. All together you make 14,204 ounces of mixture, which is 110.96875 gallons of mixture. Now for the 2/3 of 6 ounces that you have left over: You could either return those for a refund, pour them down the drain, or mix them with another 2/3 gallon of water. If you mix them, you wind up with another (89 and 1/3) ounces of mixture, which is another 0.6979 gallons of mixture.

mix 32 to 1 five times and it equals enough for five gallons
To calculate the amount of fertilizer to add for a 500 to 1 ratio, take the number of ounces of water (128 per gal X 3 = 384) and divide that amount by 500. The answer comes out to approximately three quarters of an ounce, or .768 ounces for three gallons of water.
16/23 parts mix.
Divide the number of ounces in a gallon of gasoline by the number of ounces of oil (both fluid measurements). 128/2.6=49 (about) Essentially this is a 50:1 mix. Conversely if you want a 50:1 mix divide 128 by 50. Answer is 2.56. for 2 gallons 256/50=5.1 ounces. 2-1/2 gallons of gas will take 6.4 ounces of oil.
17.6 ounces of oil for 2.75 gallons of gas to get a 20:1 mix ratio
This ratio is a 20:1 mix. Put in 32 ounces of oil for every 5 gallons of gasoline and 6.4 ounces of oil for each gallon of gasoline. If the sparkplugs get dirty too soon then change the mix to 32:1.
