The image is a color pie chart divided into 5 portions and is titled Pets Owned by Sixth Graders. <br/>Starting from the 12 o'clock position at the top and going clockwise toward the right is dark blue portion labeled Dogs, 45 percent. Next portion
If 30 sixth graders own birds, how many sixth graders were surveyed?
30 birds = 15% of the total surveyed
15% of the total surveyed = x/100
15x = 100
x = 100/15
x = 6.67
Since you can't have a fraction of a person, the number of sixth graders surveyed must be rounded up to the nearest whole number.
Therefore, 7 sixth graders were surveyed.
