Answer: 12%
Explanation:
1) Add up the number of all the swans.
5 + 34 + 2 = 41
2) Divide the number of mute swans by the total number of swans.
5/41 = 0.122
3) Move the decimal place over to spaces to the right to find the percentage.
0.122 —> 12.2%
4) Round to nearest whole percentage.
12.2% —> 12% (since the decimal was less than 0.5, it rounds down)
