Final answer:
A New York style pizza is traditionally cut into eight slices, but this can vary. The concept of slicing a pizza is related to understanding proportions and fractions.
Step-by-step explanation:
The question of how many slices are in a New York style pizza is primarily concerned with proportions and fractions, as evidenced by the examples given. When slicing pizzas or pies, the number of slices you can make depends on the size of the pizza and how you choose to cut it. For instance, slicing one pie into five pieces and taking three can be likened to how a New York style pizza might be cut into several slices.
If we think about New York style pizzas, these pizzas are traditionally large with a thin crust, and they're often cut into eight slices. However, this can vary depending on the pizza's size and the preference of the person slicing it. The examples provided mention slicing pies into different numbers of pieces, which parallels the flexibility in slicing a real-life pizza. Whether for pizza or a pie, the concept is the same: deciding on the number of slices to cut, based on what is suitable for the occasion.
