Answers and reasoning
Reveal the teacher answer key
- 8
4 ÷ 1/2 = 4 × 2 = 8.
- 4; 4
Multiply both parts by 2 and by 2.
- 24 square meters; aligned pairs (0,0), (3,6), (12,24)
12 ÷ 3 = 4 batches; 4 × 6 = 24.
- Mix B
For 36 cups water, A uses 24 cups juice; B uses 28. B has more juice per equal water amount.
- (0,0), (2,3), (4,6), (12,18); 12 tickets earns $18
Scale both quantities by each batch count; plot horizontal tickets and vertical dollars.
