Final answer:
The conversion of 300 cm to 3 m is a straightforward process where 300 cm divided by 100 equals 3 m, representing an exact correspondence between the scale and actual size without any reduction or enlargement.
Step-by-step explanation:
When converting a scale from 300 cm to 3 m, it is important to understand the relationship between these two units of measurement. Since 1 meter is equal to 100 centimeters, we can convert centimeters to meters by dividing by 100. In this case, 300 centimeters divided by 100 is equal to 3 meters, which means that the scale neither reduces, enlarges, nor preserves the size of an actual object - it represents an exact one-to-one correspondence between the scale measurement and the actual size.
