Answer:

Certainly! Here are three examples of how percentages are used in real life, along with a brief summary and identification of missing elements:

1. **Supermarket Discounts:**

- **Example**: "Save 20% on your grocery bill."

- **Summary**: In this example, the percentage (20%) represents the amount of discount you will receive on your total grocery bill. The missing element here is the total bill amount (the whole) or the specific items that are discounted (the part).

2. **Exam Scores:**

- **Example**: "You scored 90% on your math test."

- **Summary**: In this case, the percentage (90%) represents the portion of correct answers out of the total questions on the math test. The missing elements are the total number of questions (the whole) and the number of correct answers (the part).

3. **Taxation Rates:**

- **Example**: "The income tax rate is 25%."

- **Summary**: This example indicates that 25% of a person's income will be paid in taxes. The missing elements here could be the person's total income (the whole) and the actual amount of tax owed (the part).

In each of these examples, percentages are used to express a part-to-whole relationship. The missing elements may vary depending on the context, but percentages are a convenient way to convey information about proportions and rates in real-life situations.
