Find out the what is the width .
To prove
Let us assume that x be the scalar multiple of the height and width of the packaging label .
As given
The ratio of the height to the width of a packaging label is 5 to 19.
If the height of the label is 1.5 inches .
Than the equation becomes
5x = 1.5
x = 0.3
Than
The width of a packaging label = 19 × 0.3
= $ 5.7
Therefore the width of the packaging label is $ 5.7 .
