4. How do we round off, or approximate, a decimal to a required number of decimal digits?
$6.738approximately$6.74
Look at the digit to the right of the required number. If it is a 5 or greater, add 1 to previous digit.
If it is less than 5, leave the previous digit unchanged. In either case, drop all the remaining digits.
Example 1. Round off this decimal 7.253896 to three decimal digits.
Answer. 7.253896approximately7.254
(The wavy equal sign approximately means "is approximately equal to.")
To round off to three decimal digits, we must look at the digit in the fourth place. The digit in the fourth place is 8 (greater than 5). Therefore, we add 1 to the previous digit 3.
Example 2. Round off 7.253896 to two decimal digits.
Answer. 7.253896approximately7.25
The digit in the third decimal place is 3 (less than 5). Therefore, we leave the digit in the second place (5) unchanged.
Example 3. Round off 7.253896 to the nearest tenth.
Answer. 7.253896approximately7.3
To round off to the nearest tenth, means to keep one decimal digit. (To round off to the nearest hundredth would mean to keep two digits; to the nearest thousandth, three; and so on. Lesson 3, Question 5.)
Now, the digit in the second decimal place is 5. Therefore add 1 to the previous digit 2.
Example 4. Round off $6.497014
Answer. This is money. Therefore we must round off to two decimal digits:
$6.497014approximately$6.50
The digit in the third decimal place is 7 (greater than 5). Therefore, when we add 1 to 9 of 6.49, we get 6.50
To round off whole numbers, see Lesson 2.
