Answer:
The expression equivalent to 1/3b-7 is **(1/3)b - 7**.
**Here's a breakdown of the correct interpretation based on order of operations:**
1. **Parentheses and Exponents:** If there were any parentheses or exponents in the expression, we'd handle those first. But since there aren't any, we move to the next step.
2. **Multiplication and Division:** Multiplication and division are performed from left to right. In this case, we have 1/3 followed by b. The division symbol (/) directly applies to 1 and 3, indicating 1 divided by 3. So, we interpret it as (1/3)b, meaning one-third of b.
3. **Addition and Subtraction:** Finally, we perform addition and subtraction from left to right. We have (1/3)b followed by a subtraction sign (-) and then 7. This means we subtract 7 from the result of (1/3)b.
Therefore, the correct expression is (1/3)b - 7.
