A group of 10th graders, or a group of 10th grade students responded to a survey that asked which math course they were currently enrolled in. The survey data were broken down as shown above, in the table above, which of the following categories accounts for approximately 19% of all these survey respondents, so this part is very, very important. So 90% of all the survey responses is what Well 90% is another way we can write it is 19 over 100, right? 90 to 100, just 19% 90% times the total number of responses because when we do that, we'll get the number of people or students that answer it in a certain way, and that'll tell us which of the answer choices it is. So, 90 plus 90% of the total number of respondents, the total number is 310. So 19% of 310 is 58. point nine.

So where do we see something very close to 58.9? We see it right here. So we see it with males that have taken geometry. And boom, which one of the answer choices makes sense? That would be see males taking geometry. That is really the fastest way you can do it.

You can also go through each answer choice and calculate what that percentage would be. For example, for a, when they say females taking geometry while you would go to females, let me do that in different color. Females taking geometry, so that would be 53 out of 300 cent, and then you calculate then that would be less than 90%. And then you go on with B and C and D, but this is really the fastest way to do it.
