400 people found that 66 were left-handed. What percent of the 400 were left-handed?
percent= 66/400 * 100
To find the percentage of people who are left-handed out of the total population of 400, you can use the formula:
Percentage = (Number of left-handed people / Total population) * 100
In this case, the number of left-handed people is 66, and the total population is 400. Plugging these values into the formula, you get:
Percentage = (66 / 400) * 100
Simplifying the expression, you get:
Percentage = 0.165 * 100
Percentage = 16.5
Therefore, 16.5% of the 400 people surveyed are left-handed.
