Question

1. The sears Tower in Chicago is 1,450 feet tall. A model of the tower is 24 inches tall. What is the ratio of the height of the model to the height of the actual Sears Tower?
1:725
725:1
12:725
725:12

Answer 1

\(\bf 1450:24\quad ratio\implies \cfrac{1450}{24}\) simplify it by dividing both by 12, see what you get

Answer 2

hmm actually it should be the other way around so \(\bf 1450:24\quad ratio\implies \cfrac{24}{1450}\)

Answer 3

hmmm darn.... \(\bf 24:1450\quad ratio\implies \cfrac{24}{1450}\) simplify by dividing both by 12, see what you get

Answer 4

I got 1:725

Answer 5

that means \(\bf 24 \div 12 = 1?\)

Answer 6

2

Answer 7

actually, try instead dividing by 2

Answer 8

right.... so 1:725 means \(\bf \cfrac{1}{725}\) which means that \(\bf 24\div 2 = 1?\)

Answer 9

try \(\bf \cfrac{24\div 2}{1450\div 2} \)

Answer 10

12/725

Answer 11

12:725

Answer 12

yeap

Answer 13

Thank you!!!

Answer 14

No! The ratio is 1:725

24 inches to 1450 feet
2 feet to 1450 feet

\[2:1450 = 1:725\]

If the scale ratio does not specify specific units, it is assumed that you are using the same units for both numbers. 12:725 is correct only if you specify that the 12 is in inches and the 725 in feet, such as 12":725'

Answer 15

So I was right the first time. I said it was 1:725 the first time.
