Interpretation:
In a measurement scale, if the smallest markings are tenths of a millimeter, to what position the decimal point has to be marked from the given list.
Concept Introduction:
Whenever a measurement is made, there is always a degree of uncertainty or error. For example, when an object is measured with a scale having graduations in centimeter, and if the length of the object falls between 5 and 6, the estimated length would be 5.2 cm. But this value is approximate. This is called the uncertainty error. If the same scale is graduated in tenths of a centimeter, the measurement made would be with less degree of uncertainty. Hence if the markings become smaller lesser is the degree of uncertainty.
