Let's say we have the decimal 6.987654321
If we wanted to round it to the tenth decimal place, we'd write it as 6.98 because the tenth is to the second decimal place.
If we wanted to round it to the thousandth decimal place, we'd write it as 6.987.
Ten-thousandth would be 6.9876
hundred-thousandth would b 6.98765
And so on
