Mrs. Lim had a roll of ribbon that was 5.4 m long. She used 0.8 m of ribbon to wrap each small gift box and 1.2 m to wrap each large gift box. She wrapped 3 more large boxes than small boxes. After wrapping all the boxes, she had no ribbon left. How many small boxes did she wrap? Step-by-Step Solution Let the number of small boxes = ( S ). Number of large boxes = ( S + 3 ).

Remaining empty: ( 1 - \frac{7}{12} = \frac{5}{12} ) tank. 2017 psle math questions and answers

Wait — this gives ( S = 0.9 ), which is impossible (boxes must be whole numbers). This suggests that my reconstructed numbers are off; the actual 2017 question had different values (e.g., 8.4 m total ribbon, etc.), but the remains the same: form a linear equation from the total length. She wrapped 3 more large boxes than small boxes

Time needed = ( \frac{\text{remaining}}{\text{rate}} = \frac{\frac{5}{12}}{\frac{5}{12}} = 1 ) hour. Step-by-Step Solution Let the number of small boxes = ( S )
