Three in 150.With trailing zeros it can be ambiguous.One thing is certain: if you use scientific notation there is nor doubt.In scientific notation one hundred fifty can be written as1.5 * 102 in which case there are two significant figuresor it can be written as1.50 * 102 (or 15.0*101) with three significant figures [However there also is one trailing zerohere!]or as1.500 * 102 (four significant figures) this also could be expressed as 150.0 - no doubt there that there are four significant figures for zeros to the right of the decimal point!
1.6 * 102
The number 1.84 x 103 has three significant figures, 1.84. The 103 part of the number does not count when determining significant figures.
4.30 * 102. Although numerically equivalent to 4.3*102 the first shows that the number is accurate to 3 significant figures (if that IS the case), and not 2.
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.

Dividing both sides of the fraction 36/102 by 6 gives us 6/17, or six seventeenths. Expressed as a decimal fraction to three significant figures, 6/17 is equal to 0.353.

102 feet is a measurment of length, square feet is a measurement of area, to work out the square feet of an area you need two measurments lenght and width.
