Chapter 1: Problem 17

In the number \(10,046,\) how many thousands are there?

Short Answer

Expert verified
There are 0 thousands in 10,046.

Step by step solution

01

Identify the Thousands Place

In a number, the thousands place is the fourth digit from the right. In the number \(10,046\), we identify the thousands digit by counting four digits from the right, which makes the thousands digit \(0\).
02

Verify the Thousands Digit in Full Number

Rewrite the number considering its place values: \(10,046 = 1\times10,000 + 0\times1,000 + 0\times100 + 4\times10 + 6\). This confirms that the thousands digit is \(0\).
03

Determine the Total Number of Thousands

Since there is a \(0\) in the thousands place, the number of thousands in \(10,046\) is \(0\).

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Thousands Place
In understanding numbers, the thousands place is an important concept. Imagine you have a number with digits lined up. The thousands place is the position where we find which thousands are involved. It is the fourth digit from the right in any whole number.
For example, in the number 10,046, if you start counting digits from the right, you reach the thousands place at the fourth digit. Always remember this simple rule:
  • Rightmost digit is the ones
  • Next one is the tens
  • Then comes the hundreds
  • And finally, the thousands
This predictable pattern helps you locate the thousands place swiftly. If the thousands place is occupied by "0," as in 10,046, it indicates there are no complete thousands in that figure.
Digit Identification
Digit identification is a fundamental skill in understanding place values. It involves pinpointing the specific digit that represents each position in a number. Let鈥檚 take the number 10,046 again.
You need to identify each digit according to its place:
  • The ones place has the digit 6
  • The tens place has the digit 4
  • The hundreds place has the digit 0
  • The thousands place has the digit 0
Each of these digits holds a different value due to their respective positions. Knowing how to identify these can help you understand the actual magnitude of a number. It brings clarity to the overall number and makes operations like addition, subtraction, and comparison more manageable.
Number Decomposition
Number decomposition is how we break down numbers into sums of their place values. This means expressing a number by clearly defining each digit's contribution to the total based on its position.
For example, to decompose 10,046:
  • The digit 1 is in the ten-thousands place, representing 10,000 (i.e., \(1\times 10,000\))
  • The digit 0 in the thousands place adds up to 0 (i.e., \(0\times 1,000\))
  • The digit 0 in the hundreds place adds up to 0 (i.e., \(0\times 100\))
  • The digit 4 is in the tens place, contributing 40 (i.e., \(4\times 10\))
  • The digit 6 is in the ones place, contributing 6 (i.e., \(6\times 1\))
This breakdown of numbers helps visualize the value of each digit, making it easier to manipulate and understand numbers in mathematical operations. The process reinforces the ability to see numbers not just as a whole, but as the sum of parts that make it up.
