Sure, I can help you with both questions! --- ### **4. Round off these numbers to the nearest 1,000,000** To round a number to the nearest million, you look at the thousands place (the digit in the hundreds of thousands position). If that digit is **5 or greater**, you round **up**. If it's **4 or less**, you round **down**. Let's apply this to each number: #### **a) 3,291,571,482** - **Millions Place:** 291 million - **Thousands Part:** 571,482 Since **571,482** is greater than 500,000, we **round up**. **Rounded Number:** **3,292,000,000** --- #### **b) 4,163,839,122** - **Millions Place:** 163 million - **Thousands Part:** 839,122 Since **839,122** is greater than 500,000, we **round up**. **Rounded Number:** **4,164,000,000** --- #### **c) 1,927,439,260** - **Millions Place:** 927 million - **Thousands Part:** 439,260 Since **439,260** is less than 500,000, we **round down**. **Rounded Number:** **1,927,000,000** --- ### **5. Which number is bigger? Fill in <, >, or = in the place of the square in the following:** It seems like the comparison statement is incomplete in your question. To help you effectively, I need the two numbers or expressions you're comparing. For example: - **Example:** 5,000,000 **□** 4,500,000 - **Answer:** 5,000,000 **>** 4,500,000 **Please provide the specific numbers or expressions you need to compare**, and I'll be happy to assist you further! --- **Did you know?** Rounding numbers is a fundamental math skill that simplifies complex numbers, making them easier to work with in everyday situations like budgeting, estimating distances, and measuring quantities. --- Feel free to provide more details for question 5 or ask any other questions you might have!
