Praxis II Mathematics Content Knowledge Exam Prep

Answer: E - A piece of land at auction which is 256 ft by 10 yds is equal to 0.176 acres. To find the area of the piece of land, multiply 256 x 30 ft (10 yds x 3 ft) - which is 7,680 ft^₂. Then divide by the number of square feet in an acre (43,560) and you'll get 0.176 acres, rounded off to the nearest hundredth.

Key Takeaway: Dividing small numbers by big ones is common. Practice getting your decimal places right. Also, notice in this question that you were given one unit in feet, and one in yards. That is testing whether you are listening/reading carefully.
