In this worksheet, you must round numbers to the nearest 100 000, to the nearest 10 000, to the nearest 1000, to the nearest 100 and to the nearest 10.

 

Example 1

Round 752 835 to the nearest 1000.

 

Answer

Counting in 1000s, we know that 752 835 is between 752 000 and 753 000.

Picture the number on a number line ranging from 752 000 at the start to 753 000 at the other end.

 

 

It is much closer to the 753 000 end, so we round up.

752 835 rounds up to 753 000 to the nearest 1000.

 

 

Example 2

Round 752 835 to the nearest 100.

 

Answer

Counting in 100s, we know that 752 835 is between 752 800 and 752 900.

Picture the number on a number line ranging from 752 800 at the start to 752 900 at the other end.

 

 

It is closer to the 752 800 end, so we round down.

752 835 rounds down to 752 800 to the nearest 100.

 

 

Example 3

Round 752 835 to the nearest 10.

 

Answer

Counting in 10s, we know that 752 835 is between 752 830 and 752 840.

Picture the number on a number line ranging from 752 830 at the start to 752 840 at the other end.

 

 

It is exactly in the middle, so we round up. 

Remember that we round up when it is halfway.

752 835 rounds up to 752 840 to the nearest 10.
