In the original solution, you have 5 quarts total, 20% antifreeze. So 20% * 5 = 1. You have 4 qt water and 1 qt antifreeze. You will add an amount A, to this mixture. When you add, the new total volume (in quarts) is 5 + A, and the percentage is:(1 + A)/(5 + A) x 100%. So when you start out at A = zero, you have 1/5 x 100% = 20%.So set up the equation (1 + A)/(5 + A) * 100 = 30, and solve for A.Multiply both sides by (5+A) and isolate the term A. Note that since you are adding, the value of A will never be negative (so you don't have to worry about the denominator (5+A) being zero.Answer = 5/7 (quarts) = 0.714285714285155 quarts.
5 gallons is equal to 20 quarts. This means 5 gallons is greater than 19 quarts.
4 quarts in 1 gallon. 5 gallons times four equals 20 quarts. 19 quarts is not bigger than 5 gallons.
Five Percent of 20 would be 1.
6.40 because if you can find 25 percent and 5 percent you can take 5 percent from 25 percent for 20 percent.
15*20/100 = 3 quarts
30 quarts of 2 percent 15 quarts of 5 percent
5 quarts is 20 cups5 quarts is 20 cups
20 qts 1 gallon = 4 quarts 1 quart = 0.25 gallon
20% of 12 quarts= 20% * 12= 0.2 * 12= 2.4 quarts or 76.8 ounces (US measure)
There are four quarts in a gallon - the word 'quart' comes from 'quarter'. So, there are 20 ÷ 4 quarts = 5 gallons in 20 quarts.
5 gallons = 20 quarts
5 quarts is 20 cups.
There are 4 quarts in a gallon. Therefore there are 5 gallons in 20 quarts.One gallon has the same volume as four quarts.20 quarts has the same volume as five gallons (20/4=5).
1 gallon = 4 quarts so 20 gallons = 4*20 = 80 quarts. Simple!
20 quarts.
1 US Gallon = 4 quartsSince there is 4 quarts in a gallon you divide 20 quarts by 4 gallons and you will get the final answer which is 5 gallons.20 / 4 = 5 Gallons
