Answer:
1)
80 = 2×2×2×2×5
2)
21 -- 11 -- 8 -- 40
21 -- 15 -- 24 -- 60
Step-by-step explanation:
80 = 2×2×2×2×5
Half Tuna white: 21
Half brown: 21
25% of 32
25/100 × 32 = 8
32-8 = 24
Total brown: (100-20)/2 = 40
Total white = 60
Cheese:
40 - 21 - 8 = 11
60 - 21 - 24 = 15
21 -- 11 -- 8 -- 40
21 -- 15 -- 24 -- 60
