A nursery prepares a liquid plant food by adding 1 gallon of water for each 3 ounces of plant food. At this rate, how many gallons of water are required for 28 ounces of plant food? Round to the nearest hundredth, if necessary.
-
gallon/ounce = gallon/ounce
1/3 = x/28
28(1/3) = x
x = about 9.33 gallons <===
1/3 = x/28
28(1/3) = x
x = about 9.33 gallons <===
-
28 / 3 = 9 1/3 gallons or 9.33
