Sagot :
59,424.77 rounded to the nearest square mile would be 59,425 because the .77 would get rounded up to a 1. That 1 gets added to the 424, hence 59,425.
59,424.77's tenths is 7 which means we had to rounded up instead of keeping the ones, so if we add the 1 that had represented the 7 on the tenths, then 59,424+1=59,425, which means the answer would be 59,425.
