The first 3 significant digits of a number are the first 3 digits starting from the left ignoring any leading zeros.
So 31456 = 31500 (3 significant digits)
The 5 in the "56" rounds the 4 up.
1.239 rounded to 3 significant digits is 1.24
To round 233.356 to 2 significant figures, you first identify the first two non-zero digits from the left, which are 2 and 3. The digit after the second significant figure is 3. Since 3 is greater than 5, you round up the last significant figure. Therefore, rounding 233.356 to 2 significant figures gives you 230.
There are three significant digits in 60.1.
35164 is 35200 rounded to 3 significant figures. To round to 3 sig fig, use the 4th digit to decide whether to round up or down; digits after the first 3 are replaced by zeros: 4th digit is 6, so round up 35164 → 35200 to 3 sig fig.
Three. All nonzero digits are significant and zeros in between significant digits are always significant.
31500
It is 1570000 rounded to 3 significant figures
0.0195. Note that leading zeros are non-significant.
Simply cut off the extra digits: 5.00
To round numbers to 3 significant figures, identify the first three non-zero digits from the left. If the digit after the third significant figure is 5 or more, round up the last significant figure. If the digit after the third significant figure is less than 5, keep the last significant figure the same. Trailing zeroes can be kept to maintain the significant figures.
It has 3 significant digits.
3 significant digits.
No, it has 3 significant digits.
You can just round it off. For example, if your number is 8.38572998472654400131... that is equal to approximately 8.4 (if two significant digits is enough for your purposes) or 8.39 (if you prefer 3 significant digits).
1) Look at the two numbers you are multiplying 2) Find both their number of significant digits 3) Multiply both numbers together normally 4) Round your answer to the same number of significant digits of the least number in the first two factors 250 x 185 250 had 2 sig. digits------ 185 has 3 sig. digits 250 has the least number of sig. digits (2) Final answer has to have 2 sig. digits Normal answer: 46250 With rounding of sig. digits: 46000
50.4 has 3 significant digits.
