To find the percentage of cookies that is defective, we divide the number of defective cookies by the total number of cookies and then multiply by 100%.
Percentage of defective cookies = (Number of defective cookies / Total number of cookies) * 100%
Since one in 50 cookies is defective, the ratio is 1:50.
Number of defective cookies = 1
Total number of cookies = 50
Percentage of defective cookies = (1 / 50) * 100% = 2%
Therefore, the percentage of cookies that is defective is 2%.
