John decides to buy utensils. They come in 30 packs with an equal number of knives, forks, and spoons. How many packs does he need to buy if he wants 50 spoons? Give me reasons, before answering the question

Each pack contains 30 / 3 = 10 spoons. So he needs to buy 50 / 10 = 5 packs. So the final answer is 5.
