The concept of expanded form with decimals is an essential idea in mathematics, particularly when dealing with numbers that have decimal points. In this article, we will delve into the world of expanded form with decimals, using the number 74.052 as an example.
When we see a number like 74.052, it's essential to understand what each digit represents. The number can be broken down into its place values, which are the values of each digit based on its position. The place values for decimals are similar to those for whole numbers, but they are divided into tenths, hundredths, thousandths, and so on.
To understand the expanded form of 74.052, we need to break it down into its individual digits and their corresponding place values.
What is Expanded Form with Decimals?
Expanded form with decimals is a way of writing a number that shows the value of each digit in terms of its place value. It's a more detailed representation of a number, which can help us understand the relationships between the digits.
For example, the number 74.052 can be written in expanded form as:
70 + 4 + 0.05 + 0.002
This representation shows the value of each digit in terms of its place value, making it easier to understand the number's structure.
Breaking Down 74.052 into its Place Values
To break down 74.052 into its place values, we need to identify the value of each digit.
- 70 is in the tens place
- 4 is in the ones place
- 0 is in the tenths place
- 5 is in the hundredths place
- 2 is in the thousandths place
By understanding the place values of each digit, we can write the number in expanded form.
