I paused this video, did it the way he did and I got the right answer in no time. No need for x and all that. He makes it so much simpler. He said, any number after the word, "of", write it with the division line above. Then write the the other above it. So, it would like: 32 ------ 80 He then said, divide the bottom number by 100 32 -------- x 100 80 100 ÷ 80 = 1.25 1.25 '× 32 = 40% He's brilliant 😆

I tend to go at this kind of problem like this: In algebraic terms, this story problem can be expressed as: N X 80 = 32 (I dislike using "X" for unknown quantities since it can be confused with the multiplication symbol) To flip the problem around so the unknown is at the end (easier generally to process), call it: 32 divided by 80 = N So, N = .4, or 40 percent.

For anyone having issues understanding: "x" is the unknown value (percentage) as a decimal. 80*0.4 = 32 80x = 32 we want x by itself, and to do that, we can just divide 80x by 80, because that is just equal to x. but when you do that, you also have to do it on the other side of the equals sign, because the two terms are equal. If you divide on one side, but not the other it's no longer an equation. so, 80x/80 = 32/80 x = 32/80 now we have a fraction, so we simplify it to get our percentage as a decimal. 32/80 can be simplified to 4/10, because 8 divides into 32, 4 times, and into 80, 10 times. 4/10 is 0.4, so our equation will be: x = 0.4 convert that into percentage (just multiply it by 100) x = 40% therefore, option c.

I did 80x and set it equal to 32. After that it’s a simple algebra step. Think about it this way for those who may not get it, 80 × (?) = 32. If you substitute 0.4 (or 40%) for X so 80(0.4) = 32 you’ll get the equation to be equal with 32=32. Essentially your unknown is how to equal 80% to 32%. Therefore you put your variable on 80 and solve for that variable x to get the answer. 80x = 32 x = 32/80 or 0.4

Both numbers have 8 as a factor or to state it another way both are divisible by 8. 8 goes into 32 four times and 8 goes into 80 ten times, therefore 32/80 becomes 4/10 or .4 which is 40%. Note that you could have reduced it further to 2/5 but since we tend to think in multiples of 10 no further advantage is gained by doing so and 4/10 is easier to convert to decimals and percentage than 2/5 for most people.

Or you can go: 50% of 80 is 40 (easy to calculate), we're still above 32, so we need to reduce the percentage - let's calculate what 5% of 80 is, since the multiple choice answers list 45% as the highest answer below 50%, so 5% of 80 is obviously 4 (since 50% of 80 is 40, or also because 8x5/10 = 40/10), so now we have 40-4=36: 36 is still not the correct answer that we are looking for (32), so let's go 5% lower, basically subtract 4 again(from 36), oh we reach 32 here! Therefore the answer is 40% (because 50%-5%-5%=40%)

To find the percentage of one number in relation to another, you can use the formula: (Percentage / 100) * Number = Value In this case, we want to find the percentage of 32 in relation to 80. Let's assign the unknown percentage as "x": (x / 100) * 80 = 32 To solve for "x", we can divide both sides of the equation by 80: (x / 100) = 32 / 80 Simplifying the right side gives: (x / 100) = 0.4 To isolate "x", we can multiply both sides of the equation by 100: x = 0.4 * 100 x = 40 Therefore, the percentage of 80 that is equal to 32 is 40%. So, the correct answer is c. 40%.

People keep saying “there’s a much simpler way to do it”. You’re not grasping this. Memorizing formulas and not being able to derive anything isn’t math. For example. “32/80 *100” does not show you how anything works. If she explained how variables worked and how x is an input for example, it’d make more sense to most people. 80x = 32 -> x = 32/80. I can actually prove it this way. How? 80(32/80) = 32 -> 32 = 32 ✅ It’s important you know how algebra works.

@@thepistolguy859⁠ Good luck to you! I got my GED a few years back and remember how confusing math was. I want to explain why they say it the “hard way”. There’s a lot of comments saying there’s a simple way to do it such as 32/80 * 100. Which is true and it does work. They aren’t however explaining why this works and they’re missing the important details about it. Shortcuts like this aren’t good practice since you’re missing a lot of important work, unfortunately teachers on here tend to show you the right way to do it but fall flat on explaining. An important thing about this video is you need to know what a variable or x is when it comes to math. A variable x is an input. For example we know that 40% of 80 is 32. Why? Plug it in for x. 80(0.4) = 32 -> 32=32. When you’re solving for x, you’re essentially figuring out what the input value would be in order to equal your number. 80(?) = 32 -> (?) =32/80 -> (0.4) = 32/80. This is how they got the first part of their simplified version, 32 divided by 80. 80x = 32 -> x = 32/80. In order to fully understand this, let’s say we want to find out how 2 = 1 for some reason. Well we know that’s not true, but how can make an equation true? Let’s add an input variable and call it x. 2x = 1. This is the same as saying 2 * x = 1. In algebra we need to isolate the variable to solve. So, we need to divide both sides of the equation to get x by itself. 2x/2 = 1/2 -> x = 1/2. Now let’s verify if we did it right. Substitute the answer for x. 2(1/2) = 1 -> 1 = 1 ✅ Here’s a fun thought experiment. If I had a 7 mm string, how many times larger would it have to be in order for me to have a 32mm string? Build your own equation and don’t do it in your head, understand how x works. Might be a bit confusing, but the more you learn the more you realize it’s a lot more simple than you’d think. I was horrendous at math, I mean absolutely terrible at it. Failed out and got my GED. Now I’m a second year CS student doing calc 2. It may seem like they’re doing it the “hard way” but they’re doing it for a reason! Oversimplified versions that only show the end result such as 32/80*100 does not teach you math, it tells you how to memorize and never do math of your own. Understand how to derive these equations and where it comes from, if you do, math will feel very natural!

Simpler solution would be: 10℅ of 80 would be 8. So 50℅ of 80 would be its half which is 40. If we subtract 50℅-10℅ of 80 it would be 32 (40℅)

x • 80 = 32 x = 32/80 x = 40 to find x, transfer 80 to the right so we only have x on the left. divide 32 by 80 to get the value of x. Thus you have 40 which is the answer.

Make it simple, it's half means 50% is 40 units, then 40% should also 10% less Units that is 8. In mind it is very short. Another thing is cheat/spam, we can simply just multiply 8 from below numbers to get 32, whichever gives answer 32 that's the answer, in mind it's quick n easy

The % sign is just a shorthand notation for division by 100. So the answer is 40 and _not_ 40% which is 100 times smaller than the actual value.

So let's say you have 40% of 80=X... You would multiply .40×80 to get 32. In this case, you have X of 80=32. All you gotta do is the opposite. Instead of multiplying, you divide 32÷80= .40

Easy way to do it iz, 10% of any number is the number divided by 10, so 80/10 = 8, now just skip count up, so u get 8, 16 and then 32 8 = 10% 16= 20% 32= 40% U can see the percentage and numbers are just doubling

Nope. Convert the interrogative statement into a number statement: What percentage of 80 is 32? x% * 80 = 32 Since this is a percentage problem, we lay out our info in a proportion: 32 % ---- = ----- 80 100 Then cross multiply and divide to solve for x: 32 * 100 / 80 = x 3,200 / 80 = x 40 = x
