Yeah its right but if you see a more complex equation you have to go left to right so like Id go 20% of 30% which is 0.06 then multiply that by 100 and you get 6 aswell
This is just a multiplication problem with percentages -- no tricks involved. There is also more than one way to come up with the solution. I computed the answer mentally by using fractions (and shifting things around), for example.
This is a case where I wouldn't bother converting the percentages into decimal numbers. Knowing that 20% is a factor of 1/5 (i.e. you need to divide by 5), I'd either apply the 20% to 30% and get 6%, and then use the factor 100 to annul the percentage sign; or I'd do this latter step first, getting rid of the percentage sign of 30% and then calculate 30/5 = 6. But that's just a matter preference.
In this case I would read 'right to left'... Step 1: take 30% of 100, which is 30 Step 2: take 20% of this, which is one-fifth So (1/5)*30 = 6 So I thought of it as nested brackets and was able to do it in my head: (20% * (30% * 100) ) I hope that helps....
Not yet, are tree ways to find the solution and the third and more fastest way its 2×3×1= *6* . I simply canceled all the ZEROS from the numbers and from the %, that's all!! 🤣💪🤙
20% of something is 1/5 of it. So either: 30% of 100 is 30 20% (1/5) of 30 = 6 Or 20% (1/5) of 30% is 6% 6% of 100 is 6 Those are the two ways I would do it at least

What I would do is:
20% of 30% of 100
30% of 100= 30
20% of 30 =6
I think this is the right way to solve it.
I also did this only

Show off
i think as long as you properly understood the question and knew a proper method of solving it would turn out just fine

Your channel is addictive 🙏
That's exactly how I calculated it in my head. X-gen.
Thank you very clear. Excellent teaching
Very nice video 👍👍
20% of 30% is 6%
6% of 100 is 6
Love these elementary style is please do more simplifying expressions algebra videos with Powers and big division bars😊
I like your videos , learnt a lot and still learning at 50
Indeed it's a huge difference
Man, this guy is good, now if only I could remember all these math "tricks"...

Could you present more advanced mathematics. I love your way, but iam in the university and this contest is very simple
You should look up "Is This Really a Calculus Problem?"
Using fractions can be a much faster way to solve this coz all the 0s just cancel our and we are just left with 2×6=3
Oops.

I just divide 30 by 5 and call it a day.
Dude, i'm so happy that i got the answer, and it's the sam in the video some difference tho
Took about 3 seconds to figure that out.
Thanks Mr H
In this case I would read 'right to left'...
Step 1: take 30% of 100, which is 30
Step 2: take 20% of this, which is one-fifth
So (1/5)*30 = 6
So I thought of it as nested brackets and was able to do it in my head:
(20% * (30% * 100) )
I hope that helps....
You could also find 30 percenge of 100 =30 . then find 20 percent of 30 =66
hear me out:
this is just (20/100)*(3/100)*100
(1/5)*(3/10)*100
(3/50)*100
3*2 = 6
30/100•100=30
20/100•30=6
Wow, I'm smart.
You're not me tho

I love you Mr H
Hard to believe that anyone could make that mistake. But I have actually seen worse, so...
it is not difficult to calculate because it is 20/100 x 30
2/10 x 3/10 x 100/1
= 600/100
= 6
Does it work if we find 20% of 30 which is 6, and 6% of 100
Yes, they are the same steps but in different order
Multiplication is commutative, so order doesn't matter
i got 6 :)
Professor I did not know you could take a percent of a percent. per cent is not a quantity.
20% of something is 1/5 of it. So either:
30% of 100 is 30
20% (1/5) of 30 = 6
Or
20% (1/5) of 30% is 6%
6% of 100 is 6
Those are the two ways I would do it at least

(20/100)•(30/100)•100 = (20/100)•30 =600/100 : =6
