Use the information below to answer Questions 25 and 26. The pie chart below shows the different ways a group of students go to school. The number of students who travel to school by car and MRT are represented in the bar graph. How many students walk to school? Ans: ___

1. Read the number of students who travel by car from the bar graph.

$\text{Number of students who travel by car} = 220$

2. Find the total number of students using the fraction given in the pie chart.

$\frac{1}{5} \text{ of total students} = 220$
$\text{Total students} = 220 \times 5 = 1100$

3. Calculate the number of students who walk.

$\text{Students who walk} = 50\% \text{ of } 1100 = \frac{1}{2} \times 1100 = 550$
