Franco made a scale drawing of a house. The scale of the drawing was 2 millimeters = 1 meter. What is the scale factor of the drawing?

Question

Simplify your answer and write it as a ratio, using a colon.

Answer 1

To find the scale factor of the drawing, we start by using the given scale of 2 millimeters = 1 meter.

To express the scale factor as a ratio, we need to convert both measurements to the same unit. Let's convert 1 meter to millimeters.

1 meter = 1000 millimeters.

Now we can write the scale in terms of millimeters:

2 millimeters = 1000 millimeters.

The scale factor can now be expressed as a ratio:

2 millimeters : 1000 millimeters

Next, we simplify the ratio. Dividing both sides by 2 gives:

1 : 500

So, the scale factor of the drawing is:

1 : 500.
