FAQs on Printable Worksheet: Place Value and Rounding - 2 - Mathematics for Class 3: NCERT

1. What is place value and why is it important in mathematics?
Ans. Place value is the value of a digit based on its position in a number. It helps us understand the relative value of each digit in a number and how they contribute to the overall value of the number. Place value is important in mathematics as it forms the foundation for various mathematical operations such as addition, subtraction, multiplication, and division.
2. How do we round numbers and why do we need to do it?
Ans. Rounding numbers involves approximating a number to a certain degree of accuracy. This is done by determining which multiple of a given place value the number is closest to. Rounding is necessary to simplify calculations and make numbers more manageable. It also helps in representing numbers in a more practical and understandable way.
3. Can you provide an example of rounding to the nearest ten?
Ans. Sure! Let's say we have the number 58. To round it to the nearest ten, we look at the digit in the ones place, which is 8. Since 8 is greater than or equal to 5, we round the number up to the next ten, which is 60. Therefore, rounding 58 to the nearest ten gives us 60.
4. How does place value affect the rounding process?
Ans. Place value plays a crucial role in rounding numbers. When rounding, we consider the digit in the place value we want to round to. If the digit to the right of that place value is 5 or greater, we round the number up by increasing the digit in the place value we are rounding to. If the digit to the right is less than 5, we round the number down by leaving the digit in the place value we are rounding to unchanged.
5. Is place value only relevant in whole numbers, or does it apply to decimals as well?
Ans. Place value applies to both whole numbers and decimals. In whole numbers, each digit represents a power of 10, while in decimals, each digit represents a negative power of 10. Understanding place value in decimals is important for accurately representing and manipulating numbers with fractional parts.
