<h3>Given</h3>
burned : unburned = 1 : 3
<h3>Find</h3>
burned/total as a percentage
<h3>Solution</h3>
burned : total = burned : (burned + unburned) = 1 : (1+3) = 1 : 4
As a fraction, this is 1/4 = 0.25 = 25%
25% of the total cookies were burned.
_____
"%" is a fancy way to write "/100". You know from place value that 0.25 (twenty-five hundredths) is 25/100, so that can also be written as 25%.
Using proportions, it is found that the best estimate for the squirrel population is of 8000.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 43 squirrels out of 430 had tags. Considering that in the entire population, 800 are tagged, and we want to find the total population, the rule of three is given by:
43 tagged - 430 squirrels
800 tagged - x squirrels
Applying cross multiplication:



The best estimate for the squirrel population is of 8000.
