Al made a tree house last summer. He started by making a model. The model included a window with height one third in. 1/3 in. and width one fourth in. 1/4 in. The actual tree house window had height one fourth yd 1/4 yd and width three sixteenths yd 3/16 yd. Al incorrectly said that the ratio of the height of the window in the model to the height of the window in the tree house was four thirds 4/3. What was the correct ratio? What was Al 's likely error?
