The correct answer is: 222.3847

Adding "5.432" and "216.9527" requires aligning the numbers by their decimal points and then adding each corresponding column from right to left. Starting with the rightmost digit, we add the figures: - 7 + 2 = 9 - 3 + 7 = 10 (write down 0 and carry over 1) - 2 + 5 + 1 (carry over) = 8 - 6 + 4 = 10 (write down 0 and carry over 1) - 1 + 5 + 1 (carry over) = 7 - The leftmost digit is 2, which stays as is. So, combining all of these, we arrive at the total of 222.3847. This confirms that the calculations performed were accurate in terms of decimal alignment and handling of carries, leading to the correct sum. Thus, the result of adding "5.432" and "216.9527" is indeed 222.3847.
