Understanding Pictographs and Circle Graphs

A scaled pictograph uses one smiley face to represent 5 students. If there are 4 smiley faces shown for Class A, how many students are in Class A?

• 9

• 20

• 15

• 25

Answer explanation

Each smiley face represents 5 students. With 4 smiley faces, the total number of students is 4 x 5 = 20. Therefore, Class A has 20 students.

Answer explanation

The section for apples is given as \( \frac{1}{4} \) of the whole circle. This means apples represent \( \frac{1}{4} \) of the total, confirming that the correct answer is \( \frac{1}{4} \).

A pictograph shows 3 stars for books read, where each star represents 2 books. How many books were read?

• 5

• 6

• 8

• 3

Answer explanation

The pictograph shows 3 stars, with each star representing 2 books. Therefore, 3 stars x 2 books/star = 6 books read. The correct answer is 6.

If a circle graph is divided into 8 equal parts, what is the angle of each part?

Answer explanation

A circle has a total angle of 360 degrees. If divided into 8 equal parts, each part has an angle of 360° ÷ 8 = 45°. Therefore, the correct answer is 45°.

A pictograph uses one triangle to represent 10 cars. If there are 7 triangles, how many cars are there?

• 70

• 17

• 77

• 700

Answer explanation

Each triangle represents 10 cars. With 7 triangles, the total number of cars is 7 x 10 = 70. Therefore, the correct answer is 70.

Answer explanation

A circle has 360 degrees. The section for bananas is 90 degrees. To find the fraction, divide 90 by 360: \( \frac{90}{360} = \frac{1}{4} \). Thus, the correct answer is \( \frac{1}{4} \).

A pictograph shows 5 suns, each representing 4 days of sunshine. How many days of sunshine are shown?

• 9

• 10

• 20

• 25

Answer explanation

The pictograph shows 5 suns, and each sun represents 4 days of sunshine. Therefore, 5 suns x 4 days/sun = 20 days of sunshine. The correct answer is 20.

Answer explanation

A circle has 360 degrees. The fraction for sports is the shaded angle divided by the total angle: \( \frac{120}{360} = \frac{1}{3} \). Thus, the correct answer is \( \frac{1}{3} \).

A pictograph uses one heart to represent 3 pets. If there are 8 hearts, how many pets are there?

• 11

• 24

• 18

• 21

Answer explanation

Each heart represents 3 pets. With 8 hearts, the total number of pets is 8 hearts x 3 pets/heart = 24 pets. Therefore, the correct answer is 24.

Answer explanation

A circle has a total of 360 degrees. The section for reading is 180 degrees. To find the fraction, divide 180 by 360, which simplifies to \frac{1}{2}. Therefore, the correct answer is \frac{1}{2}.
