Answer 1

To solve the problem, we can set up an equation. Let's denote the number of stickers Reann started with as \( x \).

According to the problem:

1. She gives half of her stickers to her friend: This means she has \( \frac{x}{2} \) left.
2. Then her brother gives her 8 new stickers: Now she has \( \frac{x}{2} + 8 \).
3. She ends up with 12 stickers: Therefore, we can set up the equation:

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

To solve for \( x \):

1. Subtract 8 from both sides: \[ \frac{x}{2} = 12 - 8 \ \frac{x}{2} = 4 \]

2. Multiply both sides by 2: \[ x = 4 \times 2 \ x = 8 \]

So Reann started with 8 stickers.

The operations used to solve this problem are subtraction and multiplication.

Therefore, the correct response is: subtraction and multiplication.
