"<span>Heather measured a swimming pool and made a scale drawing. In real life, the pool is 45 meters long. It is 65 millimeters long in the drawing. What scale did Heather use for the drawing?"...
65mm=</span>45m<span>
Reduce to Simpliest Form.
</span>65/5=<span>45/5
13mm=9m
As a Representative Fraction (scale), it would look like: (in regards to mm)
13:9000
