To determine the scale factor in ratio form, we start with the scale that Whitney used: 8 centimeters = 2 meters.
First, we need to convert the meters to centimeters since both parts of the ratio should be in the same units. There are 100 centimeters in a meter, so:
2 meters = 2 × 100 centimeters = 200 centimeters.
Now our scale is:
8 centimeters = 200 centimeters.
Next, we can create the ratio of the drawing measurement to the actual measurement:
8 : 200.
Now we simplify this ratio by dividing both sides by their greatest common divisor, which is 8:
8 ÷ 8 : 200 ÷ 8 = 1 : 25.
Thus, the scale factor as a simplified ratio is **1:25**.
