Question

students were encouraged to wear a hat to represent their favorite place or culture. 1300 students word a hat while 800 students did not wear a hat. What percent of the school population did NOT wear a hat? (Round to the nearest whole number)

Answer 1

38%

Explanation:

You want to know the percentage of students not wearing a hat if 800 did not wear a hat and 1300 did wear a hat.

Fraction

The fraction of students not wearing a hat is their number divided by the total number of students:

800/(800 +1300) = 800/2100 = 8/21

Percentage

The percentage of students not wearing a hat is the fraction multiplied by 100%.

8/21 · 100% ≈ 38.1% ≈ 38%

About 38% of students did not wear a hat.
