Answer:

92.4%

Step-by-step explanation:

The picture is originally 11 inches wide by 8.5 inches tall.  It gets scaled down to a new width of 7 inches.  We need to find the new height.  To do this, we write a proportion:

8.5 / 11 = x / 7

Cross multiply:

11x = 59.5

Divide:

x = 5.41

The size of the picture is 5.41" x 7", but the size of the frame is 5" x 7".  The part of the picture's area that is included in the frame is:

(5 × 7) / (5.41 × 7)

= 5 / 5.41

= 0.924

92.4% of the picture is inside the frame.
