### Scale Drawings

• Scale drawing: An enlarged or reduced drawing that is similar to an actual object or place
• The scale is the ratio of the two

## The scale of a map is 2 in : 60 mi. If it is 200 mi between two cities, how many inches is it apart on the map?

• [2/50] = [x/200]
• 2 ·200 = 50x
• 400 = 50x
• [400/50] = [50x/50]
• [400/50] = x

## The scale of a map is 3 in : 30 mi. If it is 300 mi between two cities, how many inches is it apart on the map?

• [3/30] = [x/300]
• 3 ·300 = 30x
• 900 = 30x
• [900/30] = [30x/30]
• [900/30] = x

## The scale of a map is 2 in : 10 mi. If it is 300 mi between two cities, how many inches is it apart on the map?

• [2/10] = [x/300]
• 2 ·300 = 10x
• 600 = 30x
• [600/30] = [30x/30]
• [600/30] = x

## The scale drawing of King Kong is 1 in : 3 ft. If King Kong is 72 ft tall, how tall is he in the drawing?

• [l/3] = [x/72]
• 72 = 3x
• [72/3] = [3x/3]
• [72/3] = x

## The scale drawing of Godzilla is 2 in : 3 ft. If Godzilla is 45 ft tall, how tall is he in the drawing?

• [l/3] = [x/45]
• 90 = 3x
• [90/3] = [3x/3]
• [90/3] = x

## The scale drawing of a dinosaur is 1 in : 10 ft. If a dinosaur is 120 ft tall, how tall is he in the drawing?

• [l/10] = [x/120]
• 120 = 10x
• [120/10] = [10x/10]
• [120/10] = x

## A toy car is made to scale with the actual car. If the ratio of the car to the toy is 20 in : 0.5 mm, and the toy is 5 mm long, what would be the length of the actual car?

• [20 in/0.5 mm] = [x/5]
• 100 = 0.5x
• [100/0.5] = [0.5x/0.5]
• [100/0.5] = x

## A toy car is made to scale with the actual car. If the ratio of the car to the toy is 30 in : 0.6 mm, and the toy is 6 mm long, what would be the length of the actual car?

• [30in/0.6 mm] = [x/6 mm]
• 180 = 0.6x
• [180/0.6] = [0.6x/0.6]
• [180/0.6] = x

## The scale of a map is 5 in : 80 mi. If it is 40 inches between two cities on the map, how many miles apart is it?

• [5/80] = [40/x]
• 5x = 3200
• [5x/5] = [3200/5]
• x = [3200/5]

## The scale of a map is 7 in : 100 mi. If it is 2000 mi between two cities, how many inches is it apart on the map?

• [7/100] = [x/2000]
• 7 ·2000 = 100x
• [14,000/1,00] = [1,00x/1,00]
• [14,000/1,00] = x

### 140 inches
