The Expanded Form of 12.38: A Comprehensive Guide

12.38 is a decimal number that can be expanded to understand its place value and the value of each digit. In this article, we will delve into the world of decimal numbers and explore the expanded form of 12.38.

Understanding Decimal Numbers

Decimal numbers are a way of representing fractions using a point (.) to separate the whole part from the fractional part. In the case of 12.38, the whole part is 12, and the fractional part is 0.38.

Place Value of Decimal Numbers

To understand the expanded form of 12.38, we need to understand the place value of each digit. The place value of a digit is the value it represents based on its position in the number.

• The whole part (12) can be broken down into tens and ones:
  • 10 (tens)
  • 2 (ones)
• The fractional part (0.38) can be broken down into tenths, hundredths, and thousandths:
  • 0.3 (tenths)
  • 0.08 (hundredths)
  • 0.002 (thousandths)

Expanded Form of 12.38

Now that we understand the place value of each digit, we can write the expanded form of 12.38:

12.38 = (1 x 10) + (2 x 1) + (3 x 0.1) + (8 x 0.01)

Calculating the Expanded Form

To calculate the expanded form, we multiply each digit by its place value and add the results:

• (1 x 10) = 10
• (2 x 1) = 2
• (3 x 0.1) = 0.3
• (8 x 0.01) = 0.08

Adding the results, we get:

10 + 2 + 0.3 + 0.08 = 12.38

Importance of Expanded Form

The expanded form of a decimal number helps us understand the value of each digit and its contribution to the overall number. This is useful in various mathematical operations, such as addition, subtraction, multiplication, and division.

Real-World Applications

The expanded form of decimal numbers has various real-world applications, such as:

• Finance: Understanding the expanded form of decimal numbers helps in calculating interest rates, investments, and loans.
