You need to times 2/3 twice
-2/-3 * -2/3
Area and perimeter are in the ratio of 1:3. but if u mean to ask about the ratio of perimeters & areas of both triangles. the answer would be 1:1
Amount left = $450 - $171 = $279
Amount left in Percentage = 279/450 x 100 = 62%
Answer: (C) 62%
67/100 is approximately 2/3 and 515 is approximately 510 so D. 2/3*510
