Full solution

Q. A scale on a blue print drawing of a house shows that 1010 centimeters represents 22 meters.\newlineWhat number of actual meters are represented by 1818 centimeters on the blue print?\newlinemeters
  1. Identify Scale and Measurement: Identify the given scale and the measurement on the blueprint. The scale given is 1010 centimeters represents 22 meters. Measurement on the blueprint is 1818 centimeters.
  2. Set Up Proportion: Set up a proportion to find out how many meters 1818 centimeters represent.\newlineIf 1010 centimeters represent 22 meters, then 11 centimeter represents 210\frac{2}{10} meters.
  3. Calculate Meters: Calculate the number of meters that 1818 centimeters represent.\newlineNumber of meters = (18 centimeters)×(2 meters/10 centimeters)(18 \text{ centimeters}) \times (2 \text{ meters} / 10 \text{ centimeters})
  4. Perform Calculation: Perform the calculation.\newlineNumber of meters = 18×(2/10)18 \times (2 / 10)\newlineNumber of meters = 18×0.218 \times 0.2\newlineNumber of meters = 3.63.6
