Quizplus · Accepted Answer

15.234 and 15.208 both have three significant figures. When we subtract them, the result is 0.026. Since we are dealing with subtraction, we look at the number with the least number of decimal places, which in this case is 15.208 with one decimal place. Therefore, the answer should also have only one decimal place, so the appropriate number of significant figures is 2.
