All are right

To determine the number of significant figures (sig figs) in a number, follow these rules:

1. All nonzero digits are significant. For example, in the number 33.067, all the digits (3, 3, 0, 6, and 7) are nonzero, so there are five significant figures.

2. Zeros between nonzero digits are significant. In 33.067, the zero between 3 and 6 is between nonzero digits, so it is significant.

3. Leading zeros (zeros before the first nonzero digit) are not significant. In 33.067, the zero before the 3 is a leading zero and is not significant.

4. Trailing zeros (zeros after the last nonzero digit) are significant only if there is a decimal point present. In .0908, the trailing zeros are significant since there's a decimal point, so there are three significant figures.

Based on these rules:

- 33.067 has 5 significant figures.
- .0908 has 3 significant figures.
- 1099 has 4 significant figures.
- .0087 has 2 significant figures.
