Answer 1

To solve the problem, let's define the number of stickers Reann started with as \( x \).

1. She gives her friend half: This means she has \( \frac{x}{2} \) stickers left after giving away half.

2. Her brother gives her 8 new stickers: Now, she has \( \frac{x}{2} + 8 \) stickers.

3. She ends up with 12 stickers: We can set up the equation:

   \[ \frac{x}{2} + 8 = 12 \]

To solve this equation, you would need to perform:

• Subtraction (to isolate \( \frac{x}{2} \)): \( \frac{x}{2} = 12 - 8 \)
• Multiplication (to solve for \( x \)): Multiply both sides by 2 to get \( x = 4 \times 2 \).

Thus, the operations needed to solve this problem are subtraction and multiplication.

The correct response is: subtraction and multiplication.
