The difference between the quotient of three divided by one-fifth and the quotient of one-fifth divided by three can be illustrated through two distinct story scenarios that highlight the operational roles of division and how it applies to different contexts.
### Story 1: Sharing Cookies
Imagine that you have **3 cookies** and you want to share them with a group of friends. You decide to give out cookies in portions of **one-fifth of a cookie** each. To find out how many portions you can create from your 3 cookies, you perform the calculation:
\[
3 ÷ \left( \frac{1}{5} \right)
\]
This is equivalent to multiplying by the reciprocal, leading us to:
\[
3 × 5 = 15
\]
So, you can create **15 one-fifth portions** from your 3 cookies. This means that if you share cookies in tiny fractions, you will end up with 15 little portions to distribute among your friends.
### Story 2: Buying Ingredients
Now, let’s flip the scenario. Suppose you are at a baking supply store and you come across bags of flour. A bag contains **one-fifth of a pound** of flour, but you want to know how many bags you need to buy to equal **3 pounds of flour**. So, you are dividing to find out how many bags there are in 3 pounds:
\[
\left( \frac{1}{5} \right) ÷ 3
\]
This, again, leads us to a division where we can express this calculation as:
\[
\frac{1}{5} × \frac{1}{3} = \frac{1}{15}
\]
In this case, you would discover that one-fifth of a pound is only a small part of your total requirement, and thus you can see how little can be derived from it when compared to 3 pounds. Here, we find out that **one-fifth of a pound doesn't contribute much to your total need of flour** when divided by a larger quantity.
### Conclusion
These stories illustrate not only the mathematical difference between how the two quotients interact with one another but also how they can represent different real-world situations. In the first story, dividing a whole number by a fraction highlights how many small parts fit into a larger whole (3 cookies). In contrast, the second story demonstrates the inverse situation where a small quantity is being divided by a much larger quantity, showing how little you can derive from it (one-fifth of a pound).
In summary, division can be thought of as either a way of distributing items into smaller parts or as an exploration of how many smaller parts fit into a larger sum, signifying the different results based on the context of the operation.
