Detailed Solution

Concept- Here, in order to translate the unit decimeter into the unit meter, we will use the formula 1 meter = 10 decimeter.
The problem states that we must translate 1 m 4 dm into m, where m stands for the unit meter and dm for the unit decimetre.
Given that4 decimeters equals410 meters, 1 m 4 dm equals 1 m + 4 dm, or 1 m +410m, or 1 + 410m = 1 + 410= 1410 = 1.4 m. Therefore, 1 m 4 dm = 1.4 m, or 1 meter 4 decimeter = 1.4 m.
Hence, the correct option is 1.4m.
