= 80/60
=4/3

why 80?

i calculated the frame as (10+2)*(6+2)
12*8
96

the picture is 10*6 = 60

96-60=36

frame's dimensions are 14 (10 + 2 + 2) and 10 (6 + 2 + 2). add 2 on each side at both end. drawing a picture is always useful

so area with frame = 14x10 = 140
area of picture = 10x6 = 60
so the area of only frame = 140 - 60 = 80

thanks. i realized my mistake was that i accounted for only half of the frame in my calculations.

it would be 10 + (2*2)= 14
and
6 + (2*2)=10

140 - 60 =80
