rounding numbers examples Rounding means making a number simpler but keeping its value close to what it was The result is less accurate but easier to use Example 73 rounded to the nearest ten is 70 because 73 is closer to 70 than to 80 But 76 goes up to 80 Common Method There are several different methods for rounding
Here are some examples 3947 rounded to the nearest ten is 3950 3947 rounded to the nearest hundred is 3900 3947 rounded to the nearest thousand is 4000 Note that all of the digits to the right of the place you are rounding become zeros Rounding decimals works the same way For example 21 0538 rounded to the nearest Rounding numbers examples Example 1 rounding to the nearest 10 100 and 1000 Example 2 rounding to decimal places Example 3 rounding to decimal places Example 4 rounding to significant figures Example 5 rounding to significant figures Example 6 truncation Example 7 estimation

For example when rounding the number 568 to its nearest hundred the tens digit is 6 which is 5 so we add 1 to the hundred digits 5 1 6 The remaining two digits at the ones and the tens placed will be 0 So 568 becomes 600 after rounding Rounding to the Nearest Thousands Example 7 5 rounds up to 8 because 8 is an even number but 6 5 rounds down to 6 because 6 is an even number Other numbers not ending in 0 5 round to nearest as usual so 7 6 rounds up to 8 7 5 rounds up to 8 because 8 is an even number 7 4 rounds down to 7 6 6 rounds up to 7
Example If we round off 15 443 to the nearest hundred places then the answer will be 15 400 As the tens place is less than 5 the hundred place digit will not change Similarly if we round off 12 359 to its nearest hundred places then the answer will be 12 400 As the tens place is 5 the hundred place digit will change to its successor Here are some more examples 34 rounded to the nearest ten is 30 6 809 rounded to the nearest hundred is 6 800 1 951 rounded to the nearest thousand is 2 000 Rounding and Fractions Rounding fractions works exactly the same way as rounding whole numbers
