What is approximation? Write down the rules for rounding off.
Answers
Answer:
Approximation:
1. An approximation is a value or quantity that is intentionally similar but not exactly correct.
2. A number can be approximated by rounding.
Write down the rules for rounding off:
1. A number can be approximated by rounding.
2. A calculation can be approximated by rounding the values within it before performing the operations.
3. To get an accurate final result, always choose the smaller place value.
4. Look for the next smaller place which is towards the right of the number that is being rounded off to.
Approximation:
1. As we know that An approximation is a value or quantity that is intentionally similar but not exactly correct.
2. A number can be approximated by rounding.

So,
As we know An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding. A calculation can be approximated by rounding the values within it before performing the operations.
As we know If the highlighted digit is 1, 2, 3, 4 simply drop all digits to the right of the rounding digit. Example: 3.423 may be rounded off to 3.42 when rounded off to the nearest hundredth place.
