Answer:
Question 4
You have actual length of the stage is 42 feet and the scale drawing is 11cm: 7ft. Divide the 42 by 7 and the answer is 6. You would need 6 of the 7 ft increments to equal the total of the 42 ft stage. If you multiply one side of a ratio, then you have to multiply both sides. 11 x 6= 66!
Explanation:
42/7 = 6
11cm x 6: 7ft x 6
66cm: 42ft
Question 5
You have an actual length of the garage is 8 1/2 inches, or 8.5 inches on the blueprint. It take 2 of the 1/2 inch segments to get 1 inch. You need 8 1/2 or 8.5 total inches. You have to multiply 8.5 by 2 to get the total number of 1/2 inch increments that you need. 8.5 x 2 = 17. This tells you that you would need 17 of the 1/2 increments to get your total blueprint length. If you multiply one side of a ratio, then you have to multiply the other side. 17 x 1 1/2 or 1.5 = 25.5
Explanation:
1/2 inch or 0.5 inch x 2 = 1 inch
8 1/2 inches or 8.5 inches x 2 increments = 17 increments
1 1/2 ft or 1.5 ft x 17 = 25.5 ft
