How to Write One Tenth as a Decimal Step by Step

Do you know what is one-tenth? Suppose, you have 10 chocolates and you gave one to your little sister. That means you gave one-tenth of your chocolates to your sister. One-tenth is basically one part out of ten equal parts.


To write one-tenth in decimal form, first, we need to understand the meaning of one and one-tenth. Then, we will write one-tenth in decimal form.

What is One?

One is a number that represents the whole quantity. It is written as ‘1’.


What is One-tenth?

One is written in ten equal parts:

What is One-tenth


In the above-given figure, 1 is divided into 10 equal parts. The value of each part is equal to $\frac{1}{10}$ or 1-tenth.


So we can say that when one is divided into ten equal parts, then each part of the whole is equal to 0.1 and is called one-tenth.


One-tenth in Decimal Form

From the above-given figure, it is clear that if we divide ‘1’ into ten equal parts, then each part has a value of 0.1. Therefore, one-tenth is equal to 0.1.

In the above figure, if we take two parts of the whole, it will form $\frac{2}{10}$ or 2 tenth or 0.2, and so on.


Now, let us consider some more examples to understand the value of one-tenth.

One-tenth of a Circle and Decagon


Here, a circle is divided into ten wedges. All the wedges are equal and one-tenth of a circle. Similarly, if a decagon has 10 edges, all edges drawn are of equal size. Decagon is divided into 10 equal parts that form 10 equivalent triangles and each part is equal to one-tenth or decimal equivalent 0.1.


How to Get One-tenth of Any Number?

To get the one-tenth of a number, multiply it with $\frac{1}{10}$.

Some Examples Related to One-tenth of Numbers in Decimal Forms

Example 1: What is the one-tenth of 20?

Solution: One-tenth of 20 = 20 x $\frac{1}{10}$= 2

Example 2: What is the one-tenth of 100?

Solution: One-tenth of 100 = 100 x $\frac{1}{10}$ = 10

Example 3: What is the one-tenth of 75?

Solution: One-tenth of 75 = 75 x $\frac{1}{10}$= 7.5

Example 4: What is the one-tenth of 0.25?

Solution: One-tenth of 0.25 = 0.25 x $\frac{1}{10}$=0.025


Percentage Value of One-tenth

As we know one-tenth is equal to $\frac{1}{10}$, so we can find its percentage value like any other fractions. To find its percentage value, we will multiply it by 100 and add a % sign with it.

Therefore, the percentage value of one-tenth = $\frac{1}{10}$× 100% = 10 %.


Conclusion

In this article, we have learned the meaning of one-tenth, and how to write one-tenth of any number in decimal form. Understanding this concept will help you solve other sums on fractions, decimals, and percentages.

FAQs on One Tenth in Decimal Form with Definition and Examples

1. What is one tenth in decimal form?

One tenth in decimal form is 0.1. It is obtained by dividing 1 by 10. In fraction and place value terms:

  • Fraction form: 1/10
  • Decimal form: 0.1
  • Place value: 1 in the tenths place
This means one part out of ten equal parts of a whole.

2. How do you convert one tenth to a decimal?

To convert one tenth to a decimal, divide 1 by 10 to get 0.1. Follow these steps:

  • Start with the fraction 1/10
  • Divide 1 ÷ 10
  • Move the decimal point one place to the left
  • Result: 0.1
This works because dividing by 10 shifts digits one place to the right of the decimal point.

3. What does 0.1 mean in place value?

The decimal 0.1 means one in the tenths place. In the place value chart:

  • The digit 0 is in the ones place
  • The digit 1 is in the tenths place
This shows that 0.1 represents one part out of ten equal parts of a whole.

4. Is one tenth the same as 0.10?

Yes, one tenth (0.1) is equal to 0.10. Adding a zero to the right of a decimal does not change its value.

  • 0.1 = 0.10
  • Both represent one tenth
  • The extra zero is a placeholder
This follows the rule that trailing zeros after a decimal do not affect the number’s value.

5. How do you write one tenth as a percentage?

One tenth as a percentage is 10%. To convert 0.1 to a percent:

  • Start with 0.1
  • Multiply by 100
  • 0.1 × 100 = 10
  • Add the percent sign: 10%
This means 10 out of 100.

6. What is one tenth as a fraction and decimal?

One tenth as a fraction is 1/10 and as a decimal is 0.1. These are equivalent forms of the same value:

  • Fraction form: 1/10
  • Decimal form: 0.1
  • Percent form: 10%
All three represent the same quantity.

7. How do you show one tenth on a number line?

One tenth is shown at 0.1 on the number line between 0 and 1. To plot it:

  • Draw a line from 0 to 1
  • Divide it into 10 equal parts
  • The first mark after 0 is 0.1
This point represents one out of ten equal intervals.

8. What happens when you divide a number by one tenth (0.1)?

Dividing a number by 0.1 makes it 10 times larger. This is because 0.1 equals 1/10, and dividing by 1/10 is the same as multiplying by 10.

  • Example: 5 ÷ 0.1 = 50
  • Example: 12 ÷ 0.1 = 120
This is a common rule when working with decimals and fractions.

9. How do you multiply a number by one tenth?

Multiplying by one tenth (0.1) moves the decimal point one place to the left. Steps:

  • Write the number
  • Shift the decimal one place left
  • Add a zero if needed
Examples:
  • 8 × 0.1 = 0.8
  • 45 × 0.1 = 4.5
This is because multiplying by 0.1 is the same as dividing by 10.

10. Why is one tenth written as 0.1 and not 0.01?

One tenth is written as 0.1 because the digit 1 is in the tenths place, while 0.01 represents one hundredth. The place values after the decimal are:

  • First place: tenths (0.1)
  • Second place: hundredths (0.01)
So 0.1 equals 1/10, whereas 0.01 equals 1/100.
