To convert the number 0.004758 to three significant figures, we need to round it off appropriately.

  1. Identify the significant figures:

  2. Determine the significant figures based on the three most significant digits:

    • The three most significant digits in 0.004758 are 4, 7, and 5.
  3. Round the number:

    • Look at the digit immediately after the third significant figure, which is 7.

    • Since 7 is 5 or greater, we round up the third significant figure (5).
