it is reported that the wild tiger population has declined by 97% over the last 20 years.
There are now 3200 tigers left in the wild.
To the nearest thousand,how many wild tigers were there 20 years ago?

Answer :

the 3200 tigers are the 3% left from what has declined so if 3200 is 3% then you find out how much 1% is by

3200/3 and that equals 1067 and that is 1% so to find 100% you multiply it by 100 which equals 106700 tigers
