If 30 sixth graders own birds, how many sixth graders were surveyed?
Solution:
We can use the information given in the circle graph to solve this problem.
First, we need to find the total number of sixth graders surveyed. To do this, we can add up the percentages of the circle graph.
30% + 10% + 20% + 40% = 100%
This means that the total number of sixth graders surveyed is 100.
Now, we need to find the number of sixth graders who own birds. To do this, we can multiply the total number of sixth graders surveyed (100) by the percentage of sixth graders who own birds (30%).
100 x 30% = 30
Therefore, the number of sixth graders who own birds is 30, and the number of sixth graders surveyed is 100.
the way you figure it out is to do the percentages form smallest to largest
we know 5%=30
Reptiles 30
Birds 30
next percentage is 10% you will divide this the the percentage above (continue this step for rest of percentages)
Fish 10% ÷ 5% = 2
now you multiple that number by previous percentage amount you go which was 30
2 x 30 = 60 students
cats 35% ÷ 10 = 3.5
3.5 x 60 = 210 students
Dogs 45% ÷ 35% = 1.28571428571
1.28571428571 x 210 = 270 students
now add each total number of students
270+210+60+30+30 = 600 students total surveyed
