Simple Ways to Identify the Ones Place in Any Number
In general, a number's place value indicates the value of a certain digit based on that digit's position inside the number, among other factors. The one's place or unit's place refers to the location within a number. The number itself is the value of the digit in the one's position.
What is Place Value?
The term "place-value" is typically used to describe the importance of a digit in a given number based on the location of that digit inside that number. According to the number's digits, the locations in a number are ordered starting with the rightmost digit, such as the one's place, tens place, hundreds place, and so on. For instance, since 6 is in the tens place in the number 468, its place value is 60.
What is One’s Place?
One's place is defined as the first digit from the left or the rightmost position of a number. Any number's rightmost digits are referred to as the number's "one's position." The value of the digit in one's position is the same as the value of the digit itself in terms of place value. Consider the number 342, for instance. The rightmost number is 2, and its place value is 2 itself.
How to Identify One’s Place?
With the exception of integers that contain decimals, the rightmost position is regarded as the one's place. In the case of decimals, the one's place is the position immediately to the right of the decimal point. For single-digit integers, the number itself takes the place of one.
Example to Identify One’s Place
In the image above, the rightmost digit is 5. Hence, the number in the one’s place is 5
Solved Examples :
Identify the digit in the one’s place in the number 7,45,67.
Solution: Here, in the number 7,45,67 the rightmost digit is 7. Hence, the digit in one's place is 7.
Identify the digit in the one’s place in the number 72.
Solution: Here, in the number 72 the rightmost digit is 2. Hence, the digit in one's place is 2.
Identify the digit in the one’s place in the number 94.33.
Solution: Here, in the number 94.33 the rightmost digit before the decimal point is 4. Hence, the digit in one's place is 4
Identify the digit in the one’s place in the number 10,000.
Solution: Here, in the number 10,000 the rightmost digit is 0. Hence, the digit in one's place is 0.
Identify the digit in the one’s place in the number 468.23.
Solution: Here, in the number 468.23 the rightmost digit before the decimal point is 8. Hence, the digit in one's place is 8.
Conclusion
As a result, the place value is used to determine a number's digit value. The one's place is at the number's rightmost position. Therefore, it is assumed that the digit in the number's rightmost position is the one whose value equals the number itself.
FAQs on What Is the Ones Place Value in Maths?
1. What is the ones place in Maths?
The ones place is the position of the rightmost digit in any whole number. It represents the number of single units. For instance, in the number 47, the digit 7 is in the ones place, signifying seven single units.
2. How can you identify the ones place digit in a number like 358?
To identify the ones place digit, you look at the digit that is furthest to the right. In the number 358, the digit on the extreme right is 8. Therefore, the digit in the ones place is 8, and its place value is also 8.
3. How does a place value chart help in understanding the ones place?
A place value chart visually organises numbers into columns for Hundreds, Tens, and Ones. The Ones column is always the first column from the right. Placing a number into the chart clearly separates its digits, making it easy to see which digit, such as the '2' in the number '142', falls into the Ones column, representing its value of 2.
4. What is the main difference between the ones place and the tens place?
The main difference lies in their value and position.
The ones place is the rightmost position and represents single units (a value of 1).
The tens place is the second position from the right and represents groups of ten (a value of 10).
5. Can the digit 0 be in the ones place? Provide an example.
Yes, the digit 0 can certainly occupy the ones place. When it does, it signifies that there are zero single units in that position. For example, in the number 90, the 0 in the ones place indicates there are no extra units after 9 full groups of ten.
6. Why is learning about the ones place value important in Maths?
Understanding the ones place is a fundamental concept in Maths because it:
Is essential for correctly reading and writing numbers.
Forms the basis for understanding larger place values like tens, hundreds, and thousands.
Is crucial for accurately performing arithmetic operations like addition, subtraction, and carrying over.
7. Where is the ones place located in a decimal number like 12.5?
In a decimal number, the ones place is the digit located immediately to the left of the decimal point. For example, in the number 12.5, the digit 2 is in the ones place. Digits to the right of the decimal point represent fractional parts of a whole, such as tenths and hundredths.
8. What is the importance of the ones place in multiplication?
The ones place is very important in multiplication as it determines the last digit of the final answer (product). When you multiply two numbers, the digit in the ones place of the product is determined by multiplying the digits in the ones places of the original numbers. For example, to find the ones digit of 13 x 14, you only need to multiply 3 x 4 = 12. The ones digit of the final answer will be 2.
