The ratio of height to width of a tv screen is 9 to 16 how high is a screen that is 30 inches wide

Since the ratio is 9:16, that means that if the height is x inches high and the width is y inches long, x/9=y/16 Plugging 30 in for y, we get 30/16=15/8=x/9 Multiplying both sides by 9, we get x=135/8=16.875 inches

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
