Question

The ratio of the length of an airplane wong to its with is 9 to 1 the length of a wing is 43.9 meters, how wide must it be?

Answer 1

Ratio = lenght : width

L / w = 9 /1

For a 43.9 m length:

43.9 / x

Where x is the width.

Equal both ratios;

9/1 = 43.9/x

Solve for x:

9 = 43.9 /x

x= 43.9/9

x= 4.9 meters
