It's for determining the number of significant figures. Think of the U.S. in a map. The Atlantic Ocean is to the right. Pacific to left.
If a decimal is present, start counting from the "Pacific" (left).
If absent, count from "Atlantic" (right).
So, what are we counting? We count the first nonzero digit we encounter; and all subsequent digits.
E.G.: 432.30 gram has 5 sig figs.
6,000 has 1 sig fig.
The Pacific-Atlantic Rule states that when performing calculations with significant figures, you should always move from left to right just like crossing the Pacific Ocean to the Atlantic Ocean. Start calculating with the numbers on the left (Pacific) and end with the numbers on the right (Atlantic) to ensure that your final answer has the correct number of significant figures.
4 significant figures.
There are 3 significant figures in 94.2.
4487 has four significant figures.
101330 has 6 significant figures.
4 significant figures.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
There are five significant figures in the given value. It is according to the rule of significant figures which say that zeros right to the decimal point are significant and all non zero digits are significant So , all the digits in the given value are significant figures i.e 5 significant figures.
the decimal place in the quotient or product should be based in the decimal place of the given with the least significant figures
There are 2 because of the leading zeros rule. Zeros at the beginning of a number are never significant.
4 significant figures.
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
There are 3 significant figures in 94.2.
The significant figures are the first four non-zero digits - with the last of these adjusted if the following digit is 5 or more. [This is the crude school rule rather than the bias-free, IEEE approved rule.] So the answer is 2231000.
There are four significant figures in 0.1111.
3 significant figures.
4487 has four significant figures.
There are four significant figures in 0.005120.
