Q. Regan made a scale drawing of the elementary school. The scale she used was 11 millimeter : 99 meters. The actual width of the schoolyard is 6363 meters. How wide is the schoolyard in the drawing?\newline\newline____ millimeters\newline
  1. Identify scale and measurement: Identify the scale used and the actual measurement needed for conversion. Scale: 1mm:9m1\,\text{mm} : 9\,\text{m}, Actual width of schoolyard: 63m63\,\text{m}.
  2. Calculate width using scale: Calculate the width of the schoolyard in the drawing using the scale.\newlineCalculation: 63 meters9 meters/mm=7 mm \frac{63 \text{ meters}}{9 \text{ meters/mm}} = 7 \text{ mm} .
  3. Verify calculation: Verify the calculation by reversing the process.\newlineCheck: 7 mm×9 m/mm=63 m 7 \text{ mm} \times 9 \text{ m/mm} = 63 \text{ m} .
