The number of significant figures in "12,100" can be either 3 or 5, depending on whether the trailing zeros are considered significant or not. If the number is precisely 12,100 with no implied precision beyond the hundreds place, it has 3 significant figures. However, if the number is exactly 12,100.0 (implying the zeros are significant), it would have 5 significant figures. Without additional context, both interpretations are possible.
