If we colour one cube out of 1000, we get 1 or
one-thousandth. 1000

We write it in decimal form as ‘0.001’.
We read it as ‘zero point zero zero one’.

Similarly, when we colour thirteen cubes out of 1000,

we get 13 .

We write it in decimal form as ‘0.013’.

We read it as ‘zero point zero one three’.
