1. The problem states: "155 is a multiple of 5." We need to verify if this statement is true. 2. A number is a multiple of 5 if it can be expressed as $5 \times k$ where $k$ is an integer. 3. To check if 155 is a multiple of 5, divide 155 by 5: $$\frac{155}{5} = 31$$ 4. Since 31 is an integer, 155 can be written as $5 \times 31$. 5. Therefore, 155 is indeed a multiple of 5. Final answer: Yes, 155 is a multiple of 5.
