Question 926618: This is a scale/proportional word problem.
PROBLEM: The drawing of a B-17 bomber is drawn using a scale of 1 inch to 72 inches (1:72). If the wing span of the drawing is 17 inches then about how many feet long is the wing span of the actual airplane?
I solved it like this: 17x72=1224 in., then I converted inches to feet by dividing by 12 as such 1224/12 = 102 ft. Did I work the problem correctly?

Use proportion comparing ON PAPER to REAL LIVE VALUE.

. The variable R is for the real live value of the wing span. Solve for R.

-----unit of INCHES.

You can simply use one more proportion if you want FEET instead of just INCHES.
you KNOW 12 inches is 1 foot.
, using F for the amount of feet; solve for F.
