Al made a tree house last summer. He started by making a model. The model included a window with height 1/3 in. and width

1/6 in. The actual tree house window had height

1/2 yd and width

1/4 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

3/2. What was the correct ratio? What was Al's likely error? I NEED THIS ANSWER ASAP
