Question

The scale of a drawing is 2 cm : 1 mm. Is the scale drawing larger or smaller than actual object? Explain.

Answer 1

A scale of 2 cm : 1 mm, converted to millimeters, is a scale of 20 mm : 1 mm, indicating that the scale drawing is significantly larger than the actual object by a factor of 20.

Step-by-step explanation:

The scale of a drawing of 2 cm : 1 mm indicates that for every 2 centimeters on the drawing, it represents 1 millimeter of the actual object. To understand whether the scale drawing is larger or smaller than the actual object, you can convert both measurements to the same unit. Since 1 centimeter is equal to 10 millimeters, 2 centimeters is equal to 20 millimeters. So, the scale is actually saying 20 mm (on the drawing) : 1 mm (actual). This means the drawing is larger than the actual object by a factor of 20.

Answer 2

the scale of the drawing is larger than the actual object, because for every 2 centimeters shown, the actual object is 1 millimeter long.
