Decimal numbers are a vital part of our everyday lives, playing an essential role in various fields such as mathematics, finance, science, and everyday measurements. Understanding how to express decimal numbers in word form is not only a foundational skill for students but also a practical ability for adults in real-world scenarios. In this article, we will explore decimal numbers, provide a guide on how to write them in word form, and present a worksheet to practice this skill.

What are Decimal Numbers?

Decimals are a way to express fractions in a more understandable form. They are based on the base-10 number system, which consists of digits from 0 to 9. Decimal numbers can represent values that are less than one (like 0.5) or greater than one (like 1.25).

Understanding the Structure of Decimal Numbers

A decimal number is made up of two parts:

1. Whole number part: The digits to the left of the decimal point.
2. Fractional part: The digits to the right of the decimal point.

For example, in the decimal number 23.45:

• 23 is the whole number part.
• 45 is the fractional part.

Key Terms:

• Decimal Point (.): A dot used to separate the whole number part from the fractional part.
• Tenths, Hundredths, Thousandths: The positions of the digits to the right of the decimal point.

Writing Decimals in Word Form

Writing decimals in word form involves converting the digits into words. Here’s how to do it:

1. Identify the Whole Number Part: Start by writing the whole number part as you would normally spell it out. For example, for the decimal 45.67, write "forty-five".

2. Write "and" for the Decimal Point: Use the word "and" to represent the decimal point. For example, 45.67 would become "forty-five and".

3. Identify the Fractional Part: Write the fractional part, using the place value of the last digit to determine the word form. The digits in 0.67 would be read as "sixty-seven" with the place value (hundredths) mentioned.

Putting it all together, 45.67 is expressed in word form as "forty-five and sixty-seven hundredths".

Important Notes:

When writing decimals in word form:

• Always start with the whole number.

• Specify the place value (tenths, hundredths, etc.) based on the last digit.
