  • Subtitles section
  • We're asked, how many inches are in 4 and 1/2 yards?
  • And we'll do it a couple of ways.
  • One, we could just say how many inches are in 4 yards and how many inches are in a 1/2 of a yard?
  • And this really 4 plus 1/2 yards.
  • Or we could convert this into an improper fraction first and then convert.
  • But before I even do that, let's just think about how many inches there are in a yard.
  • So if I have 1 yard, we know that there are 3 feet for every 1 yard, Right?
  • And when you say, why am I multiplying by 3 instead of saying there's 1 yard for every 3 feet?
  • And the easiest way to think about it is you're going to have a larger value over here, and you're also going to want to have these units right over here cancel out.
  • So yard is canceling out with yard.
  • So you have 1 yard is equal to 3 feet, which is kind of what we already knew.
  • I'm just showing you how the dimensions cancel out.
  • And how many inches are there per foot?
  • Well, we know that there are 12 inches for every 1 foot.
  • And same logic over here, inches is a smaller unit of measurement so it makes sense that we're multiplying by 12.
  • 3 feet is going to be more inches, so we're multiplying by 12.
  • And also these units cancel out-- foot in the numerator, foot in the denominator.
  • 3 times 12 divided by 1 is equal to 36 inches.
  • So you might have already known it.
  • But this is nice to have the dimensions cancel out like this.
  • We know that 1 yard is equal to 36 inches.
  • Or there are 36 inches for every 1 yard.
  • And so we can now either break this down, or we can turn this into an improper fraction.
  • First I'll just break it down into 4 yards plus 1/2 yards.
  • So we could say that this is 4 yards.
  • So 4 yards is going to be equal to-- well, let's just multiply it times 36 inches, 36 inches for every 1 yard.
  • The yards cancel out.
  • 4 times 36 is 120, plus 24, so that's 144.
  • So this is equal to 144 inches.
  • That's just the 4 yards.
  • And then if we do the 1/2 yards, so 1/2 of a-- I guess I say 1/2 yard, once again, times 36 inches per yard, the yards cancel out.
  • 1/2 times 36 is going to be equal to 18 inches.
  • So 4 and 1/2 yards is the same thing as 4 yards plus 1/2 yards, which is the same thing as 144 inches plus 18 inches, which is going to give us-- let's just add it up over here on the right, 144 plus 18.
  • 4 plus 8 is 12.
  • 4 plus 1 is 5.
  • You have this 1 up here, so it's 6, and then we have a 1.
  • So when you add them all together, you get 162 inches.
  • The other way to do this would have been to convert this into an improper fraction and then multiply by the unit.
  • So let's do it that way.
  • If I have 4 and 1/2 of anything, really-- so let me write 4 and 1/2.
  • I'm trying to find a suitable color.
  • So if I have 4 and 1/2, this is the same thing-- 4 is the same thing as 8/2.
  • This is the same thing-- so let me write it this way.
  • 4 and 1/2 is the same thing as 4 plus 1/2, which is the same thing as-- if we want to have the same denominator as this 2 over here or as this 1/2 over here, this is the same thing as 8/2.
  • Or you could say 4/1 is the same thing as 8/2, if we want to have a common denominator, so 8/2 plus 1/2.
  • Actually, let me write it that way, just so you really understand what we're doing.
  • 4 is the same thing as 4/1.
  • So it's 4/1 plus 1/2.
  • If we want to find a common denominator, it's 2.
  • So 4/1 is the same thing as 8/2 plus 1/2, which is equal to 9/2.
  • Now, I did it this way, which takes longer, just so you really understand how we converted it, why it makes-- hopefully conceptually why it just makes intuitive sense, why 4 and 1/2 is the same thing as 9/2.
  • But if you want a simple process for it, you could just say, look, 4 times 2 is 8.
  • 8 plus 1 is 9.
  • And that gives you that 9 right over there, so 9/2.
  • So we have 9/2 yards that we want to convert to inches.
  • Same process-- times 36 inches per yard.
  • Yard in the numerator, yard in the denominator.
  • We are left with 9/2 times 36.
  • We could say times 36/1 if we like, 36 Inches for every 1 yard.
  • 36-- or the number 36 really is the same as 36/1.
  • And then we're left with just inches in our units.
  • We're just left with inches.
  • And over here there's several ways that we can simplify it.
  • Probably the easiest way to simplify it is we can divide both our numerator and our denominator by 2.
  • So let me write it this way.
  • I don't want to skip steps.
  • So we have 9 times 36 over 2 times 1, or over 2 inches.
  • And we can divide the numerator and the denominator by 2 to simplify it.
  • They're both divisible by 2.
  • 36 divided by 2 is 18.
  • 2 divided by 2 is 1.
  • So we're really just left with 9 times 18 inches.
  • We can just multiply 9 times 18.
  • Let me do it over here.
  • 18 times 9.
  • 8 times 9 is 72.
  • 1 times 9 is 9, plus 7 is 16, so we get 162 inches.
  • So all of this simplifies to 162 inches, and we are done.
