Eighty thousand whales live in the waters near Iceland. By what percent will that number be reduced, if after 10 years only 76,000 whales will remain?
95% of the whales will be dead leaving only 5% of the whole population left.
80,000/76,000=1.05263157895
Then 100/1.05263157895 which equals 95%
Opposite of that is correct. 5% of the whales are dead, while 95% are alive.
Unit rate of years to whales dead.
1 year=400 dead whales.
