Step-by-step explanation:

100 of 300 travel by bus. that is 100/300 = 1/3 if all students.

therefore, when trying to present this ratio in a pie chart, the whole circle of 360° represents all 300 students.

1/3 of 360° is 120°.

the central angle of the "slice of pie" for the 100 students traveling by bus is 120°.
