To solve the problems related to the pie chart, let's analyze the image step by step. The pie chart shows how students go to school using different modes of transportation. Here is the breakdown:
Pie Chart Breakdown:
1.
Bus: 40% of the students use the bus.
2.
Bicycle: 20% of the students use a bicycle.
3.
Car: 25% of the students use a car.
4.
Walking: 15% of the students walk.
Problem-Solving Steps:
####
Question 1: What percentage of the students go by Bus?
- From the pie chart, we can see that
40% of the students go to school by bus.
-
Answer:
40%
####
Question 2: What fraction of the students go by Bicycle?
- From the pie chart, 20% of the students go by bicycle.
- To convert 20% to a fraction:
$$
20\% = \frac{20}{100} = \frac{1}{5}
$$
-
Answer:
$\frac{1}{5}$
####
Question 3: What function of the students do not go by Bus or Car?
- First, calculate the percentage of students who go by bus or car:
$$
\text{Percentage by bus} + \text{Percentage by car} = 40\% + 25\% = 65\%
$$
- Next, calculate the percentage of students who do not go by bus or car:
$$
100\% - 65\% = 35\%
$$
- Convert 35% to a fraction:
$$
35\% = \frac{35}{100} = \frac{7}{20}
$$
-
Answer:
$\frac{7}{20}$
####
Question 4: How many students go to school by car?
- The problem does not provide the total number of students. Without this information, we cannot determine the exact number of students who go by car. However, we know that
25% of the students go by car.
- If the total number of students is given later, you can calculate the number of students going by car as:
$$
\text{Number of students by car} = \text{Total number of students} \times 0.25
$$
-
Answer:
25% of the total students
####
Question 5: How many students go to school by car or bus?
- Again, the problem does not provide the total number of students. However, we know that
65% of the students go by car or bus (as calculated in Question 3).
- If the total number of students is given later, you can calculate the number of students going by car or bus as:
$$
\text{Number of students by car or bus} = \text{Total number of students} \times 0.65
$$
-
Answer:
65% of the total students
Final Answers:
1.
40%
2.
$\frac{1}{5}$
3.
$\frac{7}{20}$
4.
25% of the total students
5.
65% of the total students
If the total number of students is provided, you can substitute it into the calculations for Questions 4 and 5 to get specific numbers.
Boxed Final Answers:
$$
\boxed{40\%, \frac{1}{5}, \frac{7}{20}, 25\% \text{ of total students}, 65\% \text{ of total students}}
$$
