That's going to depend on exactly what the '78.4' is. You haven't indicated the units of the 78.4 so there are a great many possible answers. Here are a few of them: -- If the 78.4 is a number of meters, then the nearest tenth of a meter is 78.4 meters. -- If it's 78.4 centimeters, then the nearest tenth of a meter is 0.8 meters. -- If it's 78.4 millimeters, then the nearest tenth of a meter is 0.1 meter. -- If it's 78.4 kilometers, then the nearest tenth of a meter is 78,400 meters. -- If it's 78.4 yards, then the nearest tenth of a meter is 71.7 meters. -- If it's 78.4 feet, then the nearest tenth of a meter is 23.9 meters. -- If it's 78.4 inches, then the nearest tenth of a meter is 2.0 meters. -- If it's 78.4 smoots, then the nearest tenth of a meter is 133.4 meters. -- If it's 78.4 furlongs, then the nearest tenth of a meter is 15,771.6 meters. -- If the 78.4 has no units, then it's just a naked number with no physical significance. It doesn't represent a length, or anything else, and it can't be converted to any metric quantity.
