Mr. Rodriguez asked 60 students from each grade at Willowbrook School what they liked to read, and 12 of them chose science fiction. To find out what percent that is, we can do a little math.
First, we take the 12 students who like science fiction and divide it by the 60 students he asked:
12 out of 60 is the same as 12 divided by 60, which is 0.2.
Now, we can turn that into a percent by multiplying by 100. So, 0.2 times 100 equals 20%.
Mr. Rodriguez thinks that about 20% of all the middle school students at Willowbrook like science fiction. Since there are 150 students at the school, we can imagine that if 20% of those 150 students like it, that would be:
150 times 0.2, which equals 30 students.
So, it seems like Mr. Rodriguez's guess was pretty reasonable because he asked a good number of students (60) and got a fair amount (12) who liked science fiction. That makes it likely that around 20% of all the students at the school might like it too!
