Roger wants to know whether he purchased more turkey or more cheese. Use the conversion ratio 1 kilogram = about 2.2 pounds to determine the correct answer. Show your work.
To determine whether Roger purchased more turkey or more cheese, we need to convert the weights of the turkey and cheese to a common unit of measurement.
Let's assume Roger purchased x kilograms of turkey and y kilograms of cheese.
To convert kilograms to pounds, we can use the conversion ratio 1 kilogram = about 2.2 pounds.
The weight of the turkey in pounds would be x kilograms * 2.2 pounds/kilogram = 2.2x pounds.
The weight of the cheese in pounds would be y kilograms * 2.2 pounds/kilogram = 2.2y pounds.
Since the conversion ratio is constant, we can compare the weights in pounds directly:
If 2.2x pounds (turkey) > 2.2y pounds (cheese), then Roger purchased more turkey.
If 2.2x pounds (turkey) < 2.2y pounds (cheese), then Roger purchased more cheese.
Therefore, we need to compare 2.2x and 2.2y to determine the correct answer.
