Question

The bird measures

8.58.5

cm tall in the photo and is actually

46.946.9

cm tall. Approximately how long is the​ bird's beak if it measures

1.11.1

cm in the​ photo?

The beak is

blank

cm long.

​(Round to two decimal places as​ needed.)

Answer 1

The ratio of the bird size in the photo to actual life has a constant ratio for all features of the bird (height, beak, etc.), so

bird photo height = bird photo beak length

---------------------- ------------------------------

bird real height bird real beak length

From the statement of the problem we know everything in the above proportion except bird real beak length.

We can plug in the other numbers and cross-multiply to solve for bird real beak length.
