Answer:
Total 100% or 25 students
Swimming 36% or 9 students
Lacrosse 48% or 12 students
Volleyball 16% or 4 students
Step-by-step explanation:
To do a circle graph, you draw a circle and divide it into all sections.
To know the size of each section, you need to know the total number of every category.
You could draw it with percent.
100% is total, and you know the percent of each sport.
They told you 12 students choose lacrosse so, this represents 48%.
Now, you can find the other numbers with cross-multiplication.
48%____12
100%____X=
X=(100x12)/48=25
Total students: 25
Students that named lacrosse: 12 or 48%
100%____25
16%____X=
X=(16x25)/100=4
Students that named Volleyball: 4 or 16%
100%____25
36%____X=
X=(36x25)/100=9
Students that named Swimming: 9 or 36%
To confirm: 12 + 9 + 4 = 25
