Answer:
Rounding off numbers is a mathematical technique of adjusting the number’s digits to make the number easier to use during calculations. Numbers are rounded off to a particular degree of accuracy to make calculations simpler and the results easier to understand.
It is fundamentally important to understand the term “rounding digit” when rounding off numbers.
For example, when rounding off numbers 100 to tens, the rounding digit is the second number from the right. Similarly, the rounding digit is in the third place when rounding to the nearest hundred, which is 1. Therefore, the first step when rounding a number is identifying the rounding digit and looking at the next digit to the right side.
If the digit to the right side of the rounding digit is 0, 1, 2, 3, or 4, then the rounding digit doesn’t change. All digits to the right of the rounding digit become zero.
If the digit to the right side of the rounding digit is 5, 6, 7, 8, or 9, the rounding digit increases by one digit. All the digits to the right are dropped to zero.
