    right I haven't done decimal places in a long time and something someone said to me sorta threw me off. but id just like to confirm it. so I have an answer of 4408.96 to a question and it wants it to 1.d.p. so therefore the answer is 4409.0 (1.d.p) or is it 4409?
    I thought with decimal places it always has to involve adecimal hence the name. so in this case when we do it to 1.d.p 6 is bigger than 5 and 9 increase by 1 to 10. and 1 gets added on to 4408 to make 4409, so final answer is 4409.0 so is that right?
    Also what would 1) 356.87676 be to 3 significant figures? 4 significant figures? And 5 significant figures?and what would 2) 456.289 be to 3 significant figures? and finally what would 3) 679.9756 be to 3.s.f?


    This is all basic stuff which I did back in yr6 lol but whenu spend ages with stuff like logs in a level maths and chem, I've had a slip ofmind.


    Thanks in advance

    4409.0 is right.

    Google significant figures and provide your answers before we comment further.

    I can't remember but I'm pretty sure that's all correct.
