Answer 1

1) 50 students. (Let band = x, choir = 4x, 5x = 250 → x = 50.)

2) 50 minutes. (20 pages ÷ 4 pages = 5 groups; 5 × 10 min = 50 min.)

3) 0.4 cup. (If recipe is 1/8 cup almonds per 1 cup chips → 3 × 1/8 = 3/8 = 0.375 → 0.4 rounded.)

4) 28 cups. (Soap flakes = 1 part = 7 cups; borax + washing soda = 2+2 = 4 parts → 4 × 7 = 28.)

5) 3 tsp. (Scale factor 9/6 = 1.5 → 2 × 1.5 = 3 tsp.)
