Question

How do you round 328 to the nearest hundred ?

Answer 1

Hint: Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. The most common method to round is as follows:
Step 1. Choose which is the last digit to keep.
Step 2. Leave it the same if the next digit is less than $$5$$.
Step 3. Increase it by $$1$$ if the next digit is $$5$$ or more.

Complete step by step solution:
We are asked to round 328 to the nearest hundred place, which means that round the number till all digits except hundred place are zero. We will do this by rounding the digits one after another.
The last digit to keep in 328 is 8, as the digit next to it is 2 which is less than $$5$$, thus it can be left unchanged. So, after rounding once $$328$$ can be written as $$320$$. To reach the nearest hundred place, we have to round it once more. Now, the last digit to keep is $$3$$, as the digit next it is 2. 3 is smaller than $$5$$, thus it can be left unchanged. So, after rounding $$320$$ can be written as $$300$$.
Hence, by rounding to the nearest hundred place $$328$$ can be written as $$300$$.

Note: Decimal numbers can also be round. The decimals can also be rounded similarly. For example, $$16.527$$ rounded to the nearest ten is $$16.5$$, it can be done by following the same set of rules.
