Question

Bryan randomly asked several students which type of animal they had at home as a pet. The results are in the pie chart below.

a. What percent of the students had dogs?

b. What percent of the students had birds?

c. How many total students did Bryan interview?

Answer 1

Answer: 60%, 10%, 200 students.

Explanation:

Let's start with turning all of the values into percentages.

3/5 of the students said dogs. As a percentage, 3/5 is equal to 60%.

We now have two percentages, the amount of cats and the amount of dogs. 30%+60%=90%. So that leaves 10%, and that 10 percent is the 20 students who had birds.

If 20=10%, all we have to do is multiply 20 ten times to get to 100%. 20x10=200.

There were 200 students interviewed.

Answer 2

60% of the students have dogs

10% of the students have birds

Bryan interviewed 200 students

Explanation:

a.3/5 = 60%

b.60% + 30% = 90%

100% - 90% = 10%

c. 20 x 10 = 200
