What are Underlined Digits?

Underlined digits are a way of representing a number in a specific format. In the case of the number 0.3.21, the underlined digits are 21. This means that the number can be written as 0.3 with the digits 21 written separately.

Writing the Value of Underlined Digits

To write the value of the underlined digits, we need to understand that the underlined digits are a part of the original number. In this case, the underlined digits 21 are a part of the number 0.3.21.

Breaking Down the Number

Let's break down the number 0.3.21 into its individual parts. The number can be written as:

0.3 (whole number) .21 (decimal part)

Understanding the Decimal Part

The decimal part .21 can be written as a fraction. To do this, we need to understand that the decimal part represents a fraction of the whole number.

Converting the Decimal Part to a Fraction

To convert the decimal part .21 to a fraction, we can use the following steps:

Multiply the decimal part by 100 to get rid of the decimal point.
Write the result as a fraction.

Using this method, we can convert the decimal part .21 to a fraction as follows:

.21 x 100 = 21 21/100

Writing the Value of the Underlined Digits

Now that we have converted the decimal part .21 to a fraction, we can write the value of the underlined digits 21 as follows:

21/100
