A bag of fertilizer had a ratio of 0:10:0 written on it. This means that the fertilizer contains

The ratio of 0:10:0 written on the fertilizer bag indicates the amount of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. The first number represents the percentage of nitrogen, the second number represents the percentage of phosphorus, and the third number represents the percentage of potassium. In this case, the ratio of 0:10:0 means that the fertilizer contains 0% of nitrogen, 10% of phosphorus, and 0% of potassium. Therefore, the correct option is: - 0 kg of nitrogen, 10 kg of phosphate and 0 kg of potash. It's important to note that the numbers in the ratio can be in any units, such as percentages or kilograms per ton. The ratio simply indicates the relative amounts of N, P, and K in the fertilizer.
