  1. 1 in. 6 ft Write the scale of the drawing, 1 in. = 6 ft, as . Then write a proportion in which each ratio compares inches to feet. drawing (in.) drawing (in.) actual (ft) actual (ft) 1 6 = 1n = 6(4.5) Write cross products. n = 27 Simplify. 4.5 n COURSE 2 LESSON 5-7 Maps and Scale Drawings The scale of a drawing is 1 in. : 6 ft. Find the actual length for a drawing length of 4.5 in. Let n represent the actual length. The actual length is 27 ft. 5-7

  2. Write a proportion. map (cm) map (cm) 1 75 = actual (km) actual (km) 1n = 75(4.4) Write cross products. n = 330 Simplify. 4.4 n COURSE 2 LESSON 5-7 Maps and Scale Drawings On a map of North Carolina, the map distance from Asheville to Raleigh would be about 4.4 cm. Find the actual distance from Asheville to Raleigh. The scale on the map is 1cm : 75 km. The actual distance from Asheville to Raleigh is about 330 km. 5-7

  3. 4 260 = Divide each measure by the GCF, 4. scale length actual length 1 65 COURSE 2 LESSON 5-7 Maps and Scale Drawings The actual length of the wheelbase of a mountain bike is 260 cm. The length of the wheelbase in a scale drawing is 4 cm. Find the scale of the drawing. The scale is 1 cm : 65 cm. 5-7

  4. COURSE 2 LESSON 5-7 Maps and Scale Drawings 1. The scale of a map is 1 cm : 25 km. Find the actual distance for a map distance of 6.2 cm. 2. The actual length of a machine part is 40 in. The length of the machine part in a scale drawing is 5 in. Find the scale of the drawing. 155 km 1 in. : 8 in. 5-7
