The picture will now be 7.5 inches high by 18 inches wide.
65/100 = 13/20
(divide by 5 on both sides)
Hope this helped!
You have to find a common denominator 1st then add. So 16 is the common denominator the problem should be 2 7/16+1 14/16+8-16= 3 29/16 then you need to divide 29/16 you will have 4 13/16
