bobby photographs a bird. The bird measures 9.3 cm tall in the photo and is actually 52.4 cm tall. Approximately how long is the​ bird's beak if it measures 1.1 cm in the​ photo?

1 answer

We can set up a proportion to solve for the actual length of the bird's beak:

9.3 cm (height in photo) / 52.4 cm (actual height) = 1.1 cm (length of beak in photo) / x (actual length of beak)

To solve for x, we can cross-multiply:

9.3 cm * x = 52.4 cm * 1.1 cm

Simplifying:

9.3x = 57.64

x ≈ 6.2 cm

Therefore, the bird's beak is approximately 6.2 cm long in reality.
