Question 1 Report
The bar chart shows how the students in a class travel to school.
(a) Work out the total number of students in the class. [2]
(b) Work out the fraction of the class who walk to school. Give your answer in its simplest form. [2]
Answer Details
(a) The total number of students in the class is the sum of the frequencies for every travel method shown on the bar chart: \(18 + 12 + 24 + 6\) [M1], which gives 60 [A1].
(b) The fraction who walk is the walking frequency over the total: \(\frac{24}{60}\) [M1], which simplifies (dividing numerator and denominator by 12) to \(\frac{2}{5}\) [A1].
Finding the total first in part (a) is essential before part (b) can be answered, since the fraction in part (b) depends on the total number of students found in part (a).
