if 30 sixth graders own birds how many sixth graders were surveyed theirs a pie graph with 5% reptiles 5% birds 10% fish 35% cats and 45% dogs.
Well, assuming that each kid owned exactly one animal
30 = .05 x
x =30/.05 = 3000/5 = 600
To determine the number of sixth graders who own birds, we need to use the information given in the pie graph.
We know that 5% of the pie graph represents sixth graders who own birds. From the given percentages, we also know that 30 sixth graders in total own birds, which represents 5% of the total surveyed.
To find the total number of sixth graders surveyed, we can set up a proportion:
5% (representing the 30 sixth graders who own birds) is to 100% (representing the total number of sixth graders surveyed) as 30 is to x (the unknown total number of sixth graders surveyed).
We can cross-multiply and solve for x:
(5/100) * x = 30
0.05 * x = 30
x = 30 / 0.05
x = 600
Therefore, based on the pie graph and the given information, a total of 600 sixth graders were surveyed.
