Imagining the illustration where a<span> pencil is beside a metric ruler, </span>scaled from 1 centimeter to 10 centimeters, with markings for millimeters between each number and o<span>ne end of the pencil is beside the 0 on the ruler, and the pencil point is midway between the 5 and 6, we can conclude that the precise and accurate measurement of the ruler would 5.5 centimeters. Since the point is pointing in the midway of 5 and 6, we can interpret that the point is pointing in the exact half between 5 and 6 thus we can conclude that this would be a 0.5 addition to 5, giving us the 5.5 cm.</span>
