What is 1.005 to two sig figs?
To take a number to two significant figures, you first take the greatest non-zero digit, and the one after it. In this case we'd have 1.0 Next you look at the third digit to see if the second digit should be rounded up, in this case the third digit is 0 so we don't round up. Thus the answer is 1.0, or written simply, 1

Examples in multiplication and division of significant figures?
Multiplication and DivisionRound the answer to the same number of significant figures (sig figs) as the measurement with the fewest sig figs in the problem.34.9cm x 4.7cm = 164.03cm2 = 160cm2 (rounded to two sig figs)271.0g/99.8cm3 = 2.71543g/cm3 = 2.715 (rounded to four sig figs)Addition and SubtractionRound the answer to the fewest decimal places as the measurement with the fewest decimal places.9.45kg + 8.329kg = 17.78kg (rounded to two decimal places)
How many sig figs are in 290?
There are two sig figs in 290.
How many sig figs are in 3700000?
There are two sig figs in 3700000.
How many significant figures are in 3.70 multiplied by 0.280?
There are 3 sig figs becasue when you multiply two numbers you take the same number of sig figs as the multiple with the fewest sig figs. 0.280 and 3.70 both have 3 sig figs.

How do you know how many sig figs to round to?
Determining Number of Significant Figures (Sig Figs)1.All non-zero numbers are significant. 6924 has four sig figs.2.Leading zeros are not significant. 0.0003679 has four sig figs.3.Zeros between other significant figures are significant. 0.00041092 has five sig figs.4.Trailing zeros are significant if there is a decimal. 0.046802000 has eight sig figs.Multiplication and DivisionRound the answer to the same number of significant figures (sig figs) as the measurement with the fewest sig figs in the problem.34.9cm x 4.7cm = 164.03cm2 = 160cm2 (rounded to two sig figs)271.0g/99.8cm3 = 2.71543g/cm3 = 2.715 (rounded to four sig figs)Addition and SubtractionRound the answer to the fewest decimal places as the measurement with the fewest decimal places.9.45kg + 8.329kg = 17.78kg (rounded to two decimal places)Rounding Rules:If the number to be dropped is less than four, keep the number in front the same. 3.43 would be rounded to 3.4 .If the number to be dropped is greater than five, round the number in front up by 1. 3.46 would be rounded to 3.5 .If the number to be dropped is exactly five, keep the number in front the same if it is even. If the number in front is odd, round up by 1.4.65 rounds to 4.6 .4.75 rounds to 4.8 .
How do you determine answer Sig figs for multiplication and division problem?
Look at the numbers you are multiplying and dividing. Your answer should have the amount of sig figs that the smallest number has. Rules are as followed: .00236 Has three sig figs. The zeros are used for "spacing". (.00200 also has three sig figs.) .236 Has three sig figs. 100 Has one sig fig. 100. Has three sig figs due to the decimal point. 1.00 Has three sig figs. The rules are confusing, but with practice, you should be able to understand them without a problem. I'm sure I have also forgotten to add one or two.
