The value of the 2 in the hundreds place is 200.
The value of the 2 in the ones place is 2.
Hope it helped! :)
Decimal places mean we just start counting immediately after the decimal point, so:
2dp: 0.00
1dp: 0.0
Significant figures, we start counting starting at the first non zero number
So we start counting at the 9, therefore:
2sf: 0.00097
3sf: 0.000965
To regroup is to use place value to exchange equal amount when renaming a number.
sorry for using printed paper, I tried my best to avoid the lines
