Question 5 Which division expression could this model represent? Each large square represents 1 whole. A. 3 ÷ 0.05 B. 0.5 ÷ 3 C. 3 ÷ 0.5 D. 3 ÷ 5

Answer: 3 ÷ 0.5

Explanation: Subject: Math (decimals and division, interpreting area/strip models). Each large square is 1 whole and is divided into 10 equal vertical strips, so each strip = 0.1. Two strips of 0.1 make 0.2, five strips make 0.5 (half a whole). The model groups the strips in halves (5 strips per half). There are 3 whole squares, and each whole contains 2 halves, so there are 6 halves total. That matches 3 ÷ 0.5 = 6.

Steps:

1. Note: each large square = 1 whole. Each square is divided into 10 equal vertical strips → each strip = 0.1.
2. A half (0.5) equals 5 strips (5 × 0.1 = 0.5).
3. Count halves in one whole: 1 ÷ 0.5 = 2 halves per whole.
4. With 3 wholes shown: 3 × 2 = 6 halves total.
5. Therefore the division represented is \(3 \div 0.5 = 6\).
