Over the next few weeks, I am going to be releasing short solutions to the ASVAB Mathematical Knowledge questions. If you want to see the full length video, you can find it here - • ASVAB Math Knowledge T...
Man I hope someone has made it very clear to you that what you’re doing is amazing. Some might find it unnecessary but your videos have helped me SO much.
Another method: observe “1/25” and figure that it equals 4% because multiplying “25” ,or “2.5,” by four satisfies their respective wholes, and then multiply that 4% (1/25) by six- 24% (6/25).
24% is almost 25% which is 1/4. So we need an answer that is close to but not exactly 1/4. If you look at the answers B and D are obviously nowhere close to 1/4. C is exactly 1/4 so that can't be right. Therefore it must be A.
There's also process of elimination. You can eliminate C and D because the likelihood of 24% getting into a fraction of the same denominator is pretty low. Then you look at B There's no way the fraction value of 24% is gonna be 1/25, leaving you with one plausible answer... But your way is definitely better
This is a good approach but sometimes it can breakdown into unwanted/gross decimals (what happens with 21/100?) The moment I saw the answer choices, I realized the denominators were all similar (24 or 25). Multiplying each one by 4 meant I was able to find the answer much quicker and this approach can also be used with a lower chance of issues (although some questions done with this approach would be better handled by your approach). Side note: in the case of 6/24, multiplying by 4 equals 24/96 which means something larger than 24/100
That’s true but let’s say the answer is D, not A. You’d have to do that same formula on A - C to then finally get to D which is time wasted. If you have a big brain, you can immediately eliminate B and D off rip. Then seeing 6/24 is exactly 25%, will leave you with option A. The way he’s doing it, is the fast method when it’s an even number percentage for people who want to work it out on paper. It eliminates having to divide all options and gives you the exact number. Get me?
In the event that you start with a numerator and denominator that are both even, yes. All you are ultimately doing, is multiplying by 1 in a fancy way. In general, you need to divide both numerator and denominator by factors they both have in common, until you divide by all possible common factors. Usually, the factors of 2 and factors of 5 are easiest to recognize, just by looking at the final digit, so they are good starting points.
Bro after 6th grade most ppl never do this again which leads to them forgetting how to do it Honestly I’m trying to relearn how to do all of this since I haven’t done it in like 6 years
Bro I just graduated I never wanna see this shit again-
it found you anyway >
Pizza, pie, cutting a quesiadilla for yout nephew into 4 triangles tequila shots
The answer is A
😭😭
Man lucky as mfr I’m studying to take it any tips???
Sometimes I think so fast that I really don’t think, so that makes me stupid😂
Same
These tutorials need to be called, “how not to end us as the first guy shot in the face in a war”
Bro you make me wanna go back to school 🤣 I just learn something
Me to even I never like math in High school and I’m 23 wanting to go the Marines god help me pass
@MiguelReyes-zw1dd did you pass your asvab test? If so what score??
@@MiguelReyes-zw1ddGoodluck bro, I wanna join the Coast Gaurd.
@@tsukiii8036 I’m still studying I’m giving my self 5 more weeks until I take another practice test
@@MiguelReyes-zw1ddme too I am 23 and want to join

This is how I did it, but I guess this only works on a multiple choice test.
Or just do the math
@@deltasource56 The test is timed, so if there are shortcuts it can help.
@@deltasource56 There isn't enough time in this test to do the math. I think you get an average of 40 something seconds per question.
There's also process of elimination. You can eliminate C and D because the likelihood of 24% getting into a fraction of the same denominator is pretty low. Then you look at B
There's no way the fraction value of 24% is gonna be 1/25, leaving you with one plausible answer...
But your way is definitely better
The way I got to it was that B and D are just no where near 24% and C is exactly 25% and can still be reduced, so the only answer left was A

great insight
Yooo! Simplifying the algorithm! I dig it man!
24% is about a quarter or 1/4. Now you can narrow it down to 6/25 or 6/24, but 24% is less than 6/24 so its 6/25. The 1/24 and 1/25 are non-starters.
I instantly remembered this from highschool lol
Dude thank you!!!!!
Thank you hahaha best study prep ever beast
Glad to hear it 😂
years of high school vintage me that fast enough. 👏🏽
Long division works aswell
I like this , a lot
You are awesome teacher
I wish I could do math...
Practice makes perfect
Divide every question that involves this by 2. Keep doing it and once you have the three answers there you have it. Just learned something new
What happened to finding the greatest common factor?
It is called reducing by the least common denominator.
"Cut down" being a technical term for divide by a common factor?
Yes. It's usually called reducing.
A mention of prime factors would be in order here.
I don’t miss this 😅
Thank
nice explaining
Damn this seems pretty easy
So do we always put 100 on a question like this
Yes that 100 is actually 100%
24%/100% just simplify it 24/100 : 2 = 12/50 : 2 6/25.
@@ZoejwettBro what? I’m so bad at math im feeling like you speaking in a different language 😂
You couldn’t eyeball the answer?
Nailed it
So easy
Wow that shit was easier than I thought
Got it!👍
A percentage IS a fraction.
No it’s not a percentage is a percentage
Wow u guys learn this for military exam?? I learnt this by heart in 3grade
Not learned for the military... just a check of where people are before entering.
what do you want a cookie or something 🤣
Congratulations you're a smart third-grader 🙄 do you want a biscuit 🍪
These are the ones that Army and Marines have to skip.

You cut 24 in half? How would I do that divide?
cut in half would be to divide by 2
or just look at a and c b d are not close one is high one is low just eyeball it
just 6 divided by 25 and you have your answer...
That’s true but let’s say the answer is D, not A. You’d have to do that same formula on A - C to then finally get to D which is time wasted.

Yeah, so, the answer is A. It works regardless of what the numbers are though.@@__jazzykins__

Are they all like this 😂
Is simplifying fractions really as simple as halfing the numerator and denominator? 🤦♂️
😂😂😂

You still trying to say these are ASVAB, huh?
Took the ASVAB I had like 3 of these questions
Wow...they seriously lowering it? Not like when I took it.
This is 6th grade math. I know because I teach man. We are doomed if this is an actual question for adults.
Bro after 6th grade most ppl never do this again which leads to them forgetting how to do it
Honestly I’m trying to relearn how to do all of this since I haven’t done it in like 6 years
The answer is obvious. No need to calculate.
A
Got it right
