Worksheet Overview

When we multiply numbers by 100, we do not simply add 00 to the end.

When the numbers are decimals, this rule does not work.

 

54.6 × 100 does not equal 54.600

 

When we multiply numbers by 100, each digit must move two places to the left.  

 

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

 

e.g. Work out:

 

54.6 × 100 = 5460 

 

Here is 54.6 in a decimal place value grid.

 

Decimal Place value

    5 4 . 6    

 

 

 

 

Answer:

Each digit moves two places to the left.

Remember to fill in that 0 in the ones column.

So  54.6 × 100 = 5460
