70t + 80t = 600
150t = 600 Simplify
t = 4 Divide
70(4) + 80(4) = 600 Check

Answer:
Step-by-step explanation:
Not 6 on all rolls in the diagram = 4/5
6 on all rolls in the diagram is 1/5
To find the probablity of rolling two sixes, 1/5 x 1/5 = 4/100 = 0.04 = 4%
So the complete amount of fishes were 100%
70% died and 60 are left...
so 100% - 70% = 60
100% - 70% = 30%
30% = 60 fishes...
so 10% = 20 fishes
If you complete that percentage to 100
10% = 20, 100% 200
