The scale of the drawing was 13 inches : 7 feet. The gym is 104 inches in the drawing. How wide is the actual gym?

Question

I don't know.

Answer 1

Step 1: Set up the ratio as an equation. 13in:7ft means they are in ratio, or equal. So,

 

13 inches = 7 feet, from that equation I need 104 inches, so multiply both sides of the equation by 8(whatever you do to one side, you must do to the other to keep the ratio in balance)

 

8(13 inches)=8(7 feet), which gives us 104 inches= 56 feet.

 

So the gym is actual measurement is 56 feet

Answer 2

It is actually 104/13 = 8 times as big.

So 7x8 = 56 feet.

 

SPECIFICALLY, the ratio is:

 

13 inches : 7 feet

 

13 inches: 84 inches <---- 1 foot = 12 in

 

 

13/84 = 104/?

 

84*104 = 13*?

 

? = 84*104/13 = 672 

 

672 inches = 56 feet
