Given
A frame is 9in wide and 6 in tall.
If it reduces to a width of 3 in
Find out the how tall will it be .
To proof
As given in the question
A frame is 9in wide and 6 in tall.
reduces to a width of 3 in
now as shown in the table given below
This table shows that the width of a frame is directly proportional to the height (tall) of the frame.
let us assume that the height of the frame after reduces width to 3in be = x
than the equation becomes
put the all the value
we get
solve the above
x = 2in
therefore 2in tall will be the frame .
Hence proved
