Is it possible that the leftmost bug is the smallest bug in real life? Explain your reasoning.

• Yes, because the drawing is to scale

• No, because the drawing is not to scale

• No, because the drawing is smaller than the actual size

• Yes, because the drawing is larger than the actual size

The scale of a drawing is 6 cm : 1 mm. Is the scale drawing larger or smaller than the actual object or place? Explain your reasoning.

• Larger, because the drawing length is 6 times the actual length

• Smaller, because the drawing length is 6 times the actual length

• Smaller, because the drawing length is 1/6th the actual length

• Larger, because the drawing length is 1/6th the actual length
