Q: When rounding the number 0.004567 to three significant figures, what is the result?
Solution:
Rounding to three significant figures gives 0.00457.
Steps: 6
Show Steps
Step 1: Identify the first three significant figures in the number 0.004567. The significant figures start from the first non-zero digit.
Step 2: The first non-zero digit is '4', followed by '5' and '6'. So, the first three significant figures are 4, 5, and 6.
Step 3: Look at the digit after the third significant figure (which is '7') to determine if we need to round up or keep it the same.
Step 4: Since '7' is greater than 5, we round up the last significant figure (6) by 1.
Step 5: This changes the three significant figures from 4, 5, and 6 to 4, 5, and 7.
Step 6: Write the rounded number in its original decimal form, which is 0.00457.
