Ellen separated the area of a poster into four equal sections. the perimeter of the poster is 120 inches. what is the area of each section of the poster? if ellen divides each fourth quarter of the poster into four equal parts, what fraction of the original poster is each equal part?

225; 1/16

Step-by-step explanation: After the poster is broken into 4 sections, each of the smaller sides are 15 inches. 120/8 = 15.  I am assuming that it is square. Area = LxW. 15 x 15 = 225                                                                                              1 quarter = 1/4.  1/4 divided by 4 = 1/4 * 1/4 = 1/16.  Keep Change Flip when dividing fractions.
