Question

multiply the difference of 7 and 2 by 3; 3×(7÷2); 3×(7 - 2); 3×7 - 2; 7 - 2×3

Explanation:

Step1: Analyze the phrase "difference of 7 and 2"

The difference of 7 and 2 means \(7 - 2\).

Step2: Analyze the phrase "multiply the difference by 3"

This means we take the result of \(7 - 2\) and multiply it by 3, so the expression is \(3\times(7 - 2)\).

Answer:

\(3\times(7 - 2)\) (corresponding to the second option, e.g., if the second option is labeled as B, then B. \(3\times(7 - 2)\))
