Question 4904 Deck General

The correct answer is C) dividing by the sum of the weights. The longitudinal center of gravity (LCG) is obtained by dividing the sum of the longitudinal moments by the sum of the weights. This is because the LCG represents the location of the overall center of gravity of the vessel along the longitudinal (length) axis, and it is calculated by taking the weighted average of the individual component locations. The other options are incorrect because subtracting or adding the sum of the weights would not yield the LCG, and multiplying by the sum of the weights would not provide the proper calculation to determine the LCG.
