a level maths rounding nos.! pls reply! Watch

1. If you are rounding 0.445 to 2 sf or to 2 deciamls, then would it be 0.44. This for aqa board?
2. yes it would be 0.44
3. I think it would be 0.45.
If the next digit is 0-4, round down
If it's 5-9, round up.
4. For 2 SF and 2 decimals, it would be 0.45

this is because when the last number is >5, then you round up.

This is A level?
Believe it or not, in many of the maths papers at a-level, they will not award marks for over-accurate answers, and the mark schemes state this. Best to put them to 2sf in mechanics exams and 3dp in the core ones.

Best to read the instructions at the front of the paper, where it tells you the desired accuracy.
