b. 3/4 inch
c. 15 inches
d. 1 1/2 inches

Let x be total width of the advertisement.

Since the ratio of the sum of the widths of the three pictures to the total width of the advertisement is 4:5.

Then, we have

Now, the sum of lengths of empty spaces between the pictures

=Total width - sum of width of 3 posters

From the given picture, we have

Hence, the length of each of the four empty spaces between the pictures  = 3/4 inch.
