Remember - To divide by $10$, move the decimal point one space to the left (as there is $1$ zero in $10$)

To divide by $100$, move the decimal point two spaces to the left (as there is $2$ zeroes in $100$)

To divide by $1000$, move the decimal point three spaces to the left (as there is $3$ zeroes in $1000$)

If you are dividing by a decimal, the number of zeroes tells you how many spaces to move the decimal places to the right:

$0.1$ = $1$ zero, $1$ space to the right;

$0.01$ = $2$ zeroes = $2$ spaces to the right;

$0.001$ = $3$ spaces to the right.

This is useful to know as:

Dividing by $0.1$ = Multiplying by $10$

Dividing by $0.01$ = Multiplying by $100$

Dividing by $0.001$ = Multiplying by $1000$

Don't forget to round your answers to 3 decimal places!!
