## Rounding to the Nearest Hundredth

Rounding is a process in which we convert a given number into an easy number for various purposes. This easy number is not the exact value but is an approximate value of our number.

## Purpose of Rounding

We generally round number because:

• The rounded number is easier to understand and remember.
• The calculations become easier to work with.

## Applications of Rounding

Some of the applications of rounding are as follows:

• Estimation- If we want to estimate an answer or try to work out the most sensible guess, rounding is widely used to facilitate the process of estimation.

For instance: Josh wants to buy a laptop and knows it would cost approximately $950. But he rounds off this number and takes$1,000 instead, to be sure that he has enough money to buy the machine even if it costs a few dollars more.

## Rounding Numbers to the Nearest Hundredth

To round numbers to the nearest hundredth, we follow the given steps:

Step 1- Identify the number we want to round.

Step 2- Mark the digit in the hundredth column.

Step 3- Now we look at the ‘thousandths’ column (the digits to the right of the hundredth column).

Step 4- (i) If the digit in the thousandths column is 0, 1, 2, 3 or 4, we will round down the hundredth column to the nearest hundredth.

(ii) If the digit in the thousandths column is 5, 6, 7, 8 or 9, we will round up the hundredth column to the nearest hundredth.

Step 5- Remove all the digits after the hundredth column. The left out number is our desired answer.

The process of rounding numbers to the nearest hundredth is shown using the given examples:

Example 1- Round 4.1257 to the nearest hundredth.

Example 2- Round 53.183 to the nearest hundredth.

Example 3- Round 6.698 to the nearest hundredth.

Example 4- The depth of the pond is 73.789 m. What will be its depth rounded to the nearest hundredth?

Example 5- Bank Z has an exchange rate of 1.8962 Pounds to the Dollar. Round the exchange rate to the nearest hundredth. Understanding Decimals
