Identify the operations (addition, subtraction, division, multiplication) in forming the following expressions and tell how the expressions have been formed.
`17y, y/17 , 5z`

Answer

To solve the problem, we need to identify the operations used in forming the given expressions: `17y`, `y/17`, and `5z`. Let's analyze each expression step by step.

### Step 1: Analyze the expression `17y`
- The expression `17y` can be interpreted as `17 multiplied by y`.
- Therefore, the operation used here is **multiplication**.

### Step 2: Analyze the expression `y/17`
- The expression `y/17` indicates that `y` is being divided by `17`.
- Hence, the operation used here is **division**.

### Step 3: Analyze the expression `5z`
- The expression `5z` can be interpreted as `5 multiplied by z`.
- Thus, the operation used here is also **multiplication**.

### Summary of Operations
- For `17y`: The operation is **multiplication** (17 * y).
- For `y/17`: The operation is **division** (y ÷ 17).
- For `5z`: The operation is **multiplication** (5 * z).
