# Decimal Place Value – Definition, Examples, Practice Problems

At Brighterly, we believe that understanding decimals and their place value is a crucial skill for children learning mathematics. Through our comprehensive and interactive approach, we aim to make learning fun and engaging. In this blog post, we will delve into the fascinating world of decimals and place value, providing clear explanations, real-life examples, and interactive practice questions to strengthen your child’s understanding and foster a lifelong love for mathematics.

## What is Decimal Place Value?

Decimal place value is the value of each digit in a decimal number based on its position relative to the decimal point. Just as in whole numbers, the position of a digit in a decimal number determines its value. Each place to the right of the decimal point is worth ten times less than the one immediately to its left.

For example, in the number 42.37:

• The digit 4 is in the tens place, making it worth 40.
• The digit 2 is in the ones place, making it worth 2.
• The digit 3 is in the tenths place, making it worth 0.3.
• The digit 7 is in the hundredths place, making it worth 0.07. ### Dividing Whole Numbers By Decimals Worksheet PDF

## Decimal Place Value Chart

A decimal place value chart is a visual representation of the values of the digits in a decimal number. It helps in understanding and identifying the place value of each digit in a decimal number. The chart typically shows columns for each decimal place, including whole numbers, tenths, hundredths, and so on. Using a decimal place value chart can help children gain a better understanding of the decimal system and how the value of each digit is determined by its position in the number.

## Decimal Chart to Hundredths

A decimal chart to hundredths is a chart that shows decimal numbers up to the hundredths place. It is useful for teaching children about decimal place value and for comparing and ordering decimal numbers. The chart can be organized in various ways, such as by rows and columns, and can include whole numbers, tenths, and hundredths.

## About Decimal Place Value System

The decimal place value system is a way of representing numbers using a base-10 system. In this system, each position in a number has a value that is a power of 10. The decimal point is used to separate the whole number part from the fractional part. The place values to the right of the decimal point are tenths, hundredths, thousandths, and so on, with each place being worth ten times less than the one to its left. Understanding the decimal place value system is essential for working with decimals in various mathematical operations, such as addition, subtraction, multiplication, and division.

## Standard Form

The standard form of a decimal number is the most common way of writing decimal numbers, with the digits arranged according to their place value and separated by a decimal point. For example, the standard form of the number “four and thirty-seven hundredths” is written as 4.37.

## Expanded Form

The expanded form of a decimal number shows the value of each digit in the number, separated by addition symbols. For example, the expanded form of the number 4.37 is written as 4 + 0.3 + 0.07, indicating the value of each digit in the number.

## Writing Decimal Numbers in the Decimal Place Value

Writing decimal numbers in the decimal place value system involves placing each digit in its correct position relative to the decimal point. To do this, identify the place value of each digit and write the number accordingly. For example, to write the decimal number 0.528:

• The digit 5 is in the tenths place.
• The digit 2 is in the hundredths place.
• The digit 8 is in the thousandths place.

So, the number is written as 0.528.

## Understanding the Decimal Place Value Chart

To understand the decimal place value chart, start by recognizing that each column represents a different place value. From left to right, the place values decrease by a factor of ten. The chart can be used to help visualize the position of each digit in a decimal number, making it easier to understand the value of each digit and perform mathematical operations with decimals.

## Decimal Place Value Examples

Let’s look at some examples to further illustrate the concept of decimal place value:

1. In the number 7.14:

• The digit 7 is in the ones place.
• The digit 1 is in the tenths place.
• The digit 4 is in the hundredths place.
2. In the number 0.009:

• The digit 0 is in the tenths place.
• The digit 0 is in the hundredths place.
• The digit 9 is in the thousandths place.

## Practice Questions on Decimal Place Value

Here are some practice questions to test your understanding of decimal place value:

1. What is the value of the digit 3 in the number 0.831?
2. Write the number “six and twenty-five hundredths” in standard form.
3. Write the expanded form of the number 12.09.
4. Arrange the following decimal numbers in ascending order: 0.45, 0.2, 0.12, 0.3.

## Frequently Asked Questions on Decimal Place Value

### What is the difference between decimal place value and whole number place value?

Decimal place value refers to the value of digits in a decimal number, while whole number place value refers to the value of digits in a whole number. In both systems, the value of each digit is determined by its position relative to the decimal point or ones place, but decimal place values decrease by a factor of ten moving to the right of the decimal point.

### How do you round decimal numbers?

Rounding decimal numbers involves adjusting the value of a decimal number to a specified place value. To round a decimal number, look at the digit immediately to the right of the desired rounding place. If this digit is 5 or greater, increase the digit in the rounding place by 1. If the digit is less than 5, leave the digit in the rounding place unchanged. All digits to the right of the rounding place are removed.

### Why is understanding decimal place value important?

Understanding decimal place value is important because it forms the foundation for working with decimal numbers in various mathematical operations, such as addition, subtraction, multiplication, and division. It also helps children develop number sense and the ability to compare, order, and estimate decimal numbers.
