When we divide numbers by 100, each digit must move two places to the right.  

When we look at the columns in a Th, H, T, O grid we notice that tens are 100 times smaller than thousands, ones are 100 times smaller than hundreds etc...

Example

Work out 54.6 ÷ 100 

Here is 54.6 in a place value grid.

Answer

Each digit moves two places to the right.

Remember to fill in that 0 in the ones column.

54.6 ÷ 100 = 0.546 

Let's have a go at some questions now.
