Three.
0.3 has one significant figure.
The number 02 has one significant figure because a leading zero is not significant. So the significant figure is the digit 2.
2000 has one significant figure. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
There are two significant figures in 1200 kilograms.
One - all nonzero digits are significant. Yes, but embeded 0s are also counted. 102 has 3 sig digs. Secondly, trailing 0s (0s on the right hand side of the number) are significant if they are an indication of the degree of accuracy, but not otherwise.
(if there is to be one significant figure) 2 * 102(if there are to be two significant figures) 2.0 * 102 (if there are to be three significant figures) 2.00 * 102
We need to first move the decimal two (2) places to the left: 480 = 4.80 x 102 The 2 in 102 comes from how many places we moved the decimal. It's positive because the number it represents is larger (480 > 4.8) With one significant figure, we need to round to the nearest whole number: 5 x 102 The answer is 5 x 102
