Problem
A craft store has 540 packs of yarn on sale. The store sells \( 65 \% \) of the packs by the end of the day. Determine if each statement about this situation is correct. Choose Yes or No for each statement. a. The expression \( 540 \div 0.65 \) can be used to find how many packs were sold. Yes \( \square \) No b. The store has 189 packs left. Yes \( \square \) No c. The store sold 351 packs. Yes \( \square \) No d. The store has \( 45 \% \) of the packs left. \( \square \) Yes \( \square \) No
Solution
Step 1 ：\( \frac{540}{0.65} \) can't be used, use \( 540 \times 0.65 \)
Step 2 ：Calculate: \( 540 \times (1 - 0.65) = 189 \)
Step 3 ：Calculate: \( 540 \times 0.65 = 351 \)
Step 4 ：Packs left: \( 100\% - 65\% = 45\% \)
