If 20 3rd graders owned birds, how many third graders were surveyed?
Reptiles 5%
Birds 5%
Fish 10%
Cats 35%
Dogs 45%
I did 5% of 30 = .05 x 30 = 1.5
30/1.5 = 20 third graders
BUT I am thinking I am doing something wrong? Where did I go wrong?
Should it be 30/.05 = 600 students were surveyed?
I want to understand my steps on where I messed up? Could you show me?
Oops I meant 30 third graders.
To find the number of third graders surveyed, you did the following calculation:
5% of 30 = 0.05 x 30 = 1.5
Then, you divided 30 by 1.5 to get 20 third graders.
However, in this case, the information you provided about the percentages of different pets seems to be unrelated to the question of how many third graders were surveyed. The percentages you mentioned appear to represent the distribution of different pets among the surveyed students rather than the overall percentage of students owning each type of pet.
To find out how many third graders were surveyed, you need to look for relevant information or assumptions provided in the question or additional context. If no such information is given, you won't be able to deduce the number of third graders surveyed from the given data about pet percentages.
