Mario draws a scale drawing that includes a ladybug. The actual ladybug is 8 millimeters long. The ladybug in Mario's drawing is 2 centimeters long. What is the scale factor that Mario uses to make his drawing?

Scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing.

In this case the ladybug is 8 mm long but drawing length is 2 cm.

Let’s convert both into the same units

2 cm - 20 mm

Original - 8 mm

Painting - 20mm

X - scale factor

20 = X * 8

X = 20/8 = 2.5

The ladybug has been multiplied / enlarged by a scale factor of 2.5 to draw the painting
