show all appropriate work on loose leaf paper to be submitted as a single pdf for the file response question at the end of the test. the answer in the answer box is worth 1 point and the work is worth 4 pts.

Explanation:

Question 19: Analyze the division diagram

We count the total number of small items (trees/arrows) in the diagram. There are 3 groups, and each group contains 3 items.

$$ \text{Total items} = 3 \times 3 = 9 $$

The total of 9 items is divided into 3 equal groups, with 3 items in each group. This represents the division fact:

$$ 9 \div 3 = 3 $$

Question 20: Convert Roman numeral MCMLXV

We break down the Roman numeral \(MCMLXV\) into its standard additive and subtractive components:

• \(M = 1000\)
• \(CM = 1000 - 100 = 900\)
• \(L = 50\)
• \(X = 10\)
• \(V = 5\)

We sum these values to find the Indo-Arabic equivalent:

$$ 1000 + 900 + 50 + 10 + 5 = 1965 $$

Answer:

Question 19

\(9 \div 3 = 3\)

Question 20

1965
