The official width-to-length ratio of the United States flag is 1:1.9. If a United States flag was 9.5 feet long, how wide would it be? ... ?

Ok so lets say that w will denote the actual width. we can rewrite

1:1.9 as 1/1.9=10/19 so:

10/19=w/9.5

or we can also write it as,

10/19=10w/95

If you try to solve the equation to get the value of w, it would be 5 at the end.
