Understanding Decimal Numbers in Word Form

Decimal numbers are a fundamental concept in mathematics, and being able to express them in word form is an essential skill. In this article, we will explore how to convert decimal numbers to word form, focusing on the example of seventy-eight point six.

The Basics of Decimal Numbers

Decimal numbers are a way of expressing fractions using a decimal point. The decimal point separates the whole number part from the fractional part. For example, the decimal number 78.6 can be broken down into its whole number part (78) and its fractional part (0.6).

Converting Decimal Numbers to Word Form

To convert a decimal number to word form, we need to consider both the whole number part and the fractional part. Here are the steps:

• Start by converting the whole number part to word form. For example, the whole number part of 78.6 is 78, which can be written as "seventy-eight."
• Next, convert the fractional part to word form. For example, the fractional part of 78.6 is 0.6, which can be written as "six tenths."

Writing the Fractional Part in Word Form

The fractional part of a decimal number can be written in word form using the following rules:

• If the fractional part is less than 1, write it as a fraction with the numerator being the digit(s) after the decimal point and the denominator being the place value of the digit(s). For example, 0.6 can be written as "six tenths."
• If the fractional part is greater than or equal to 1, write it as a whole number followed by the fraction. For example, 1.6 can be written as "one and six tenths."

Putting it All Together

Now that we have converted both the whole number part and the fractional part to word form, we can put them together to write the decimal number 78.6 in word form.
