Decimals: Dividing by 10

When we divide numbers by 10, each digit must move one place to the right.  

When we look at the columns in a Th, H, T, U grid we notice that Hundreds are 10 times smaller than Thousands, Tens are 10 times smaller than Hundreds etc...

*Note that the U for Units is another term for Ones.

Work out:

546 ÷ 10 = 54.6 

Here is 546 in a Th, H, T, U grid.

Answer:

Each digit moves one place to the right.

So, 546 ÷ 10 = 54.6.
