Question 917824: The length, width and height of a hall are in the ratio 6 : 1 : 9 and the width is 7 metres. What is the height in metres?

Do you add the ratio, so it would be 6 + 1 + 9 = 16 then divided it by 7? so the answer would be....

If the length, width and height of a hall are in the ratio 6 : 1 : 9,
then that hall is 9 times as tall as it is wide. A 6 : 1 : 0.9 ratio makes more sense.

If the length, width and height of a hall are in the ratio 6 : 1 : 0.9,
width and height are in the ratio 1 : 0.9, meaning
width%2Fheight=1%2F0.9 .
In this case,
7meters%2Fheight=1%2F0.9--->%287meters%29%2A0.9=1%2Aheight-->highlight%28height=6.3meters%29
