So in this problem, you're given a pie chart, and it looks like it shows the reading preferences for grade four students.
00:07
So in number one, it says a survey asked 200 grade four students about their reading preferences.
00:12
We want to figure out approximately how many of them would we prefer to use a comic book.
00:17
So notice the comic book is in this section right here.
00:20
So first, we want to figure out approximately what percentage of that circle is actually comics.
00:26
Well, if it was cut like this, that would be about 25%.
00:29
So this is going to be a little bit more than 25%, but not anything closer to a half.
00:34
So first, we have to figure out what 25 % of 200 is.
00:37
Well, 25 % is a 4, so we're going to take 1 fourth and multiply by 200.
00:43
Well, 4 goes into 200 50 times...
