Understand the Problem
The question presents a math examination with various tasks that require students to solve problems involving expanded forms, place values, and numeral representations.
Answer
1. Expanded form: $$4000 + 300 + 90 + 0$$ 2. Place value of 5: **Thousands** 3. Represented number: $$1023$$ (based on visual blocks - confirm visually).
Answer for screen readers
-
Expanded form of 4390: $$4000 + 300 + 90 + 0$$
-
Place value of 5 in 4563: Thousands ($5000$)
-
If represented number is based on assumed blocks: $$1023$$ (confirm based on visual provided).
Steps to Solve
-
Writing 4390 in Expanded Form
To write the number 4390 in expanded form, we break it down into its place values:
- The digit 4 is in the thousands place, so it represents $4 \times 1000 = 4000$.
- The digit 3 is in the hundreds place, so it represents $3 \times 100 = 300$.
- The digit 9 is in the tens place, so it represents $9 \times 10 = 90$.
- The digit 0 is in the ones place, so it represents $0 \times 1 = 0$.
Thus, the expanded form of 4390 is:
$$4390 = 4000 + 300 + 90 + 0$$
-
Finding the Place Value of 5 in 4563
In the number 4563, the digit 5 is in the thousands place. Therefore, the place value of 5 is:
- Thousands: The place value is $5 \times 1000 = 5000$.
-
Identifying the Number Represented
The question features a visual representation not available in this text. However, if a 1000 block, 100 block, 10 block, or a 1 block is used, the total number can be summed based on the count of each. For example, if there are:
- 1 thousand block
- 0 hundred blocks
- 2 ten blocks
- 3 one blocks
Then, the number represented would be:
$$1 \times 1000 + 0 \times 100 + 2 \times 10 + 3 \times 1 = 1000 + 0 + 20 + 3 = 1023$$
-
Expanded form of 4390: $$4000 + 300 + 90 + 0$$
-
Place value of 5 in 4563: Thousands ($5000$)
-
If represented number is based on assumed blocks: $$1023$$ (confirm based on visual provided).
More Information
- The expanded form helps illustrate the value of each digit in a number based on its position.
- Understanding place value is essential for grasping larger numerical concepts.
- The visual representation, if related to base ten blocks, conveys the value of numbers in different forms.
Tips
- Confusing the position of a digit leading to an incorrect place value.
- Not including zero in the expanded form may lead to misunderstanding.
