You have a bowl with 200 fish in it. of these fish 99% are not guppies. how many fish should you remove so that 2% of what remains are guppies

Find how many are not guppies now

99% of 200 are not guppies
100-99=1
1% of 200 is guppies
2 are guppies

now

2=2% of all
2=0.02 of all
divide both sides by 0.02
100=all

you need to have 100 left
you need to remove
200-?=100
-?=-100
?=100
you need to remove 100 non-guppy fish so that 2% of what remains is guppies
