Question

Darell made a scale drawing of a swimming pool. He used the scale 9 inches = 4 feet. What scale factor does the drawing use? Simplify your answer and write it as a fraction.

Answer 1

The scale factor represents the ratio between the measurements on the drawing and the actual measurements of the swimming pool.

Since the scale is 9 inches = 4 feet, we can simplify it by dividing both sides by 3. This gives us a scale of 3 inches = 1.33 feet, or approximately 1.33/1 feet.

To express this as a fraction, we can simplify the decimal by multiplying both the numerator and the denominator by 100, which gives us 133/100.

So the scale factor of the drawing is 133/100.
