Answer explanation

Significant figure rules for addition tell us that the first answer has to have 1 decimal place. When we divide the 3 significant figures from the original numbers tell us that our answer has to have 3 significant figures. We have to ignore the number 4 because it is simple the total number of figures there are for us to divide by, therefore it does not count in the significant figure rules.
