    How do i do this with any decimal number?

    and also, how do i round decimals to 1 significant figure?

    For example for:
    0.003 4672

    How do i round that to 1SF and to the nearest 10, 100 and 100?

    thank you!

    So your example rounded to the nearest 100 would be 0.003
    Thing is, you cat round to zero, so you can't round any higher in that example, if it were 0.10345455 you could round it to 0.1

    Assuming that you meant round to the nearest tenth, hundredth and thousandth the answers would be:

    0.0034672 \approx 0.0,
    0.0034672 \approx 0.00,
    0.0034672 \approx 0.003.

    Rounding to the nearest 10,100 and 1000 you will get 0 each time.

    Rounding the same number to various numbers of significant figures you get:

    0.0034672 \approx 0.003 (one significant figure)
    0.0034672 \approx 0.0035 (two significant figures)
    0.0034672 \approx 0.00347 (three significant figures)
    0.0034672 \approx 0.003467 (four significant figures)
    0.0034672 \approx 0.0034672 (five significant figures)
