 This is another example another video of examples of percent problems in this example We have I have a little bit of a different problem here to get into that problem at Clayton High School 434 students or 35 percent of the students play a sport. How many students does Clayton High School have? Okay, so in this in this picture Excuse me in this problem. What we want to do is just like last time I want to identify any numbers that I might use so as I read through this I see 434 students and I see 35 percent those are two numbers that I recognize right away I will probably use those we'll see where they go. All right now Just like last time that says this is a percent type of problem. I'm going to use my handy little Again formulas what I'll call for now percent over a hundred is equal to parts over all Okay, so again this proportion helps us to solve percent problems This is one of the one of the easier ways to help us solve percent problems, okay? So at Clayton High School 434 students or 35 percent of students play a sport. How many students does Clayton High School have? So as I read through this I want to identify Okay, what is the percent number? What is the part number? What is the whole number? Those are the three variables if you will there's the three unknowns that I have and As I read through this I'm going to figure out what those unknowns are and plug them in So one thing that I see right away one thing I can figure out is right here 35 percent I know exactly where that's going to go that's going to go in my percent spot right here So 35 over 100 that starts out my little formula here Now I got to figure out what the part is and what the hole is do I know the part? Do I know the hole? So in this case when we're talking about a school We're talking about parts of the students or we're talking about the whole student body Okay, so as I reread this This this number that comes up is just just part of the student body or is this the whole student body? Is there's the question do you want to answer? at Clayton High School 434 students or 35 percent of students play a sport at Clayton High School 434 students play a sport notice. I skipped what was in the parentheses there 434 students play a sport now that to me that tells me that's only part of the student body That's not everything. That's only part of the students So as I look at my little formula that 434 is going to go in the part spot 434 and right here might is my whole student body. How many students does Clayton High School have? That's what we're trying to answer. What's the whole student body? All right, so I need a variable for this since I'm using Clayton since it's a high school. We use H I mean you use whatever variable you want. You can use X. You can use a he's whatever you want to I'm just gonna use H for high school doesn't really matter what we use as long as we understand what the variable means Okay, so now as before this is a this is a Proportion type of problem. What I'm gonna do is I'm gonna use cross product to solve this cross product cross multiply Whatever you want to call it. So in this case 35 times H is 35 H equals 100 times 434 that's actually pretty easy to use so I'm going to write that out as 434 2 extra zeros on the end 434 times 100 is 43,400 And just a little bit simple math there. All right, then next What I'm going to do is I'm going to divide by 34. Nope, not 34 35. Excuse me divide by 35 So H in this case is equal to that I cannot do in my head So I'm going to use my handy-dandy off the screen here to figure out that that is going to be 1240 Okay, now once you get down to this part now remember for my last video H equals 1240 1240 that that makes no sense Nobody is going to know what that means make sure when you have a problem like this make sure you actually answer the question So what I'm going to do is take that Interpret that answer and write down Or excuse me interpret what this variable means and write down actually what my answer is so in this case H is equal to 1240 I chose H to be the whole student body How many students does Clayton high school have? H tells me the whole school. It tells me every student that's in that school Okay, so what my answer would be that Clayton high school Clayton high school Has 1240 total students And being very being very precise there. I'm saying Clayton high school That's the school I'm talking about has 1240 total students I use that extra total word there to make sure that whoever's reading this knows exactly what that means That's the total number of students that go to that high school 1240 that seems like to be a pretty big high school Anyway, that is another example of percent problems I will think I will do one more in another video to help us out with these type of percent problems
