In a hydroponic farming system, a nutrient solution is created by mixing a liquid fertilizer concentrate with water in a ratio of to by volume. To fill a reservoir, a technician needs to prepare a total of liters of this nutrient solution. How many liters of the liquid fertilizer concentrate are required to prepare the solution?
Cevap: 18 liters
Cevap
18
To find the amount of liquid fertilizer concentrate needed, we first express the ratio in terms of the total mixture. The ratio of concentrate to water is to , meaning there are parts of concentrate for every parts of water, making a total of parts. Since the total volume of the solution is liters, each part represents liters. The amount of concentrate required is parts, which corresponds to liters.
