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...
e.g. Work out:
54.6 ÷ 100 = 0.546
Here is 54.6 in a place value grid.
Each digit moves two places to the right.
Remember to fill in that 0 in the ones column.
So 54.6 ÷ 100 = 0.546
