Final answer:
To determine the number of pickles needed for 8 ham slices, we can set up a proportion using the conversion factor provided. Cross-multiplying and solving the equation, we find that 20 pickles are needed.
Step-by-step explanation:
To determine how many pickles are needed, we can use the given information that 5 pickles combine with 2 ham slices in each sandwich. We are asked about the number of pickles needed, so we need to find a conversion factor between the number of ham slices and pickles. From the information given, we know that 5 pickles combine with 2 ham slices, so the conversion factor is 5 pickles / 2 ham slices.
To find the number of pickles needed, we can set up a proportion using the conversion factor: 5 pickles / 2 ham slices = x pickles / 8 ham slices. Cross-multiplying, we have 2 * x pickles = 5 * 8 pickles. Simplifying, we get 2x = 40, so x = 20.
Therefore, 20 pickles are needed to combine with 8 ham slices.
