To find the answer, we first need to calculate the proportion of students who prefer walking. This can be found by dividing the number of students who prefer walking (145) by the total number of students (500). Accordingly,
145 รท 500 = 0.29
So, 0.29 or 29% of the total students prefer walking.
Next, we need to convert this proportion to a percentage to make it easier to understand. We do this by multiplying the proportion (0.29) by 100:
0.29 * 100 = 28.999999999999996 %
Rounding off to the nearest whole number, we can say that approximately 29% of the students prefer walking to school.
