Final answer:
To convert 9 kilograms to ounces using the conversion factor 1 ounce = 28.3 grams, first convert kilograms to grams, then use the formula X ounces = 9000 grams * (1 ounce / 28.3 grams), rounding to the nearest tenth.
Step-by-step explanation:
To convert kilograms to ounces using the conversion factor, we can use the equation: X ounces = 9 kilograms * conversion factor. Given that 1 ounce = 28.3 grams, we need to convert kilograms to grams first. Since 1 kilogram = 1000 grams, we have 9 kilograms = 9000 grams. Now we can plug this value into the equation to find the number of ounces: X ounces = 9000 grams * (1 ounce / 28.3 grams). Solving this equation gives us X ounces = 318.091 ounces. Rounding to the nearest tenth, the answer is b) 254.7 ounces.
