Chapter 1: Problem 2

Find the value of 5 in the number 65,000 .

Short Answer

Expert verified
The value of 5 in 65,000 is 5,000.

Step by step solution

01

Identify the Place Value

In the number 65,000, the digit 5 is in the thousands place. It is important to determine the place value of the digit to understand its contribution to the total number.
02

Calculate the Value of the Digit

Since the digit 5 is in the thousands place, it represents five thousand or 5,000. This can be calculated by multiplying the digit 5 by 1,000.

Key Concepts

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

Thousands Place
In numbers, each digit holds a specific place value, which determines its contribution to the number's overall value. In this context, we focus on the thousands place. The thousands place is located four places to the left of the decimal point.
In simpler terms:
  • The rightmost digit is the ones place.
  • Next is the tens place.
  • Then comes the hundreds place.
  • Finally, we have the thousands place.
This sequence increases by a power of ten as you move left. In the number 65,000, the digit '5' occupies the thousands place, signifying thousands count. This makes a huge difference in understanding not just 'what' that number is but why each digit matters. Recognizing the thousands place helps break down large numbers into manageable units, aligning with how we count real-world items.
Value of Digits
Every digit in a number has a specific value based on its place value. The value of the digits depicts how much each digit contributes to the overall number. Let's explore what this means, such as in our given example of 65,000.
The digit '5' at this point is not just '5'. Instead:
  • It signifies 5,000, based on its placement in the thousands column.
  • This creates a clear distinction from if the '5' were in the ones or tens place, where it would mean '5' or '50' respectively.
Using this framework makes it possible to break down large numbers, explaining their makeup. Grasping the concept of digit value is essential for performing more complex arithmetic operations and for understanding the makeup of any given number.
Multiplication in Place Value
People often wonder how place value relates to multiplication. It's all about assigning a value through multiplication. Specifically, each position is a power of 10, which serves as the "multiplier" for that digit. Here鈥檚 how it works.
Imagine our example number 65,000:
  • To gauge the value of the digit '5' in the thousands place, you multiply the digit by 1,000.
  • The calculation becomes: \(5 \times 1,000 = 5,000\).
The principle is the same across any digit and position, and using multiplication allows us to quantify the substantial role each plays. This systematizes the understanding of big numbers into something much more digestible and is crucial for quick, accurate mathematical transformation and real-life application.
