Write an example of a part to whole ratio.

Sure, I'd be happy to help you with that! A part-to-whole ratio compares the relationship between a specific part and the whole of something. Let's say we have a basket of fruit containing 5 apples, 3 oranges, and 2 bananas. The part-to-whole ratio of apples to the total number of fruits in the basket would be 5:10 (since there are 10 fruits in total).

To calculate this ratio, follow these steps:
1. Identify the specific part you want to compare to the whole.
2. Count the number of that specific part (e.g., apples).
3. Count the total number of items in the whole (e.g., all fruits in the basket).
4. Express the count of the specific part as a ratio with the count of the whole.

In this example, we have 5 apples as the specific part and a total of 10 fruits in the basket. So, the part-to-whole ratio of apples to fruits would be 5:10 or simplified to 1:2.
