Question

hassan thinks his goldfish got chickenpox. He lost 70% of his collection of goldfish. If he has 60 survivors , how many did he have originally??

Answer 1

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
