Understand that significant figures (sig figs) are the digits in a number that carry meaningful information about its precision.
Identify the digits in the number 160: the digits are 1, 6, and 0.
Determine if the trailing zero is significant. In a number without a decimal point, trailing zeros are generally not considered significant.
Since 160 has no decimal point, the trailing zero is not significant, so only the digits 1 and 6 are significant.
Conclude that the number 160 has 2 significant figures.
