How do you find sig figs when multiplying and dividing?
How do you find sig figs when multiplying and dividing?
For multiplication and division use the following rule: The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer. (You are now looking at the entire number, not just the decimal portion)
Which digits are significant WS?
1) All digits 1-9 inclusive are significant. Example: 129 has 3 significant figures. 2) Zeros between significant digits are always significant.
Do trailing zeros count sig figs?
The trailing zeros do not count as significant. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0, and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant).
What is the rule for rounding when multiplying and dividing?
Where should we round it off? That answer comes from the rule for significant digits used in multiplication and division: Round the answer to the shortest number of significant digits in the numbers you are multiplying or dividing. The shortest number of significant digits is 2 (in the 3.0 x 104).
How many significant figures does 0.100 have?

How to determine how many SIG figs are in a number?
A. Rules for determining how many Sig Figs are in a number: Rule #1: Non-Zero digits (# 1 – 9) and Zeros that are in between two non-zero digits are always significant. Rule #2: Leading zeroes are never significant. Rule #3: Trailing zeroes are only significant if a decimal point is present in the number.
