I'm 70 now and still learning.
Hi Josh thank you so much for this video very useful? I have a question for you, I came a cross with decimal 0.3846153846 How do you get to its fraction 5/13? I found this one difficult.
Thanks for the question... For 0.3846153846 the repeat is 384615. As a fraction this is therefore 384615/999999, which after a bunch of simplification becomes 5/13.
I have not needed to this since carpentry school, but I've always liked learning ways to compute still. I've said it before but I'll say it again, 'where were your videos 25 years ago when I was in high school?' great videos
There is a better shortcut trick for converting mixed recurring decimals to fractions. Take for example the last number shown : 0.91666.... Step 1: Subtract the number 916 by the number formed by non repeating digits i.e 91 => 916-91 = 825 Step 2: Divide the number above by a number formed by taking as many 9's as the number of repeating digits and add as many trailing zeroes as there are digits after the decimal which are not repeating => 825/900 = 11/12
thank you I have learnt this trick in the past and forgot, was just going through the internet to again learn this trick but couldn't find it. Cant believe I found this trick in the comment section
Thanks for the video, I really appreciate your hard work for this, I just thank you for your teaching because I'm having problems with it. But thanks for your video! And god bless us all. ❤🙏😊
Dang. I guess I’m so rusty what I need is how to mentally see that 1875 is divisible by 25. I see it has a five, but I guess does the 75 in the tens-units place tell me it’s divisible by 25?
I forgot this math. I'm going into plumbing and this math was in the text book and I panicked thinking I was too dumb but it's actually easy. It's like a puzzle and you showed us the algorithm to solve any kind.
With regard to the problem 0.9166666...., there is the following option so that you have easier calculations. 0.9 = 9/10 and .0166666....=1/6 but our problem was slightly different. So if we divide 0.16666.... by 10, it becomes 0.016666.... = 1/60. So merely add 9/10 and 1/60, which equals 55/60 that reduces to 11/12.
When you finally get a math teacher that explains and doesn't complain at you being stupid for not being able to solve a math problem despite being asian
In the example using 0.1666, when you multiply it by 100, in every other example it was the same ending with the numbers pushed up, I thought that 0.1666.. x 100 would be, 16.6666, why is that not the case? Why it is instead 16.666 if it's repeating
All of this (at least here in Italy) is taught at the 8-year-olds of the third year of elementary school (and recurring decimals are much simpler than that and require zero algebra). Do adults seriously need UA-cam now?
Multiply 25 by 4 to get 100. 1800 consists of 18 hundreds 18 × 4 to mentally calculate this, double it twice. 18 -> 36 -> 72 there is still 75 left (1800 vs 1875). Add 3 that you get from 75/25 72 + 3 = 75
A similar method is to do this: 0.732424242424 Take the total decimal pattern right up until you start repeating (including the repeated part), i.e. 7324 Then subtract the part that isn't repeated, i.e. 7324 - 73 = 7251 This is the numerator. The denominator will be a number that has the same number of 9s as the repeated pattern's digits, followed by the same number of 0s as the non-repeated pattern's digits The repeated pattern is 24 (two digits), and the non-repeated pattern is 73 (two digits), therefore, the denominator is 9900. So, 0.73242424.... = 7251 / 9900, which can be "simplified" to 2417 / 3300 - of course I use the term "simplified" loosely. And just to prove this wasn't a fluke, here's another example: 0.8472195195195195195195.... Take the decimal part up to, and including the repeated part, i.e. 8472195 Then subtract the non-repeated part, i.e. 8472195 - 8472 = 8463723 (this will be the numerator) Now, we take the repeated part, which is 195, and put the same number of 9s as the number of digits in the repeated part, i.e. 999 Then we take the non-repeated part, which is 8472, and put the same number of 0s as there are digits in the non-repeated part, after the 999, to get 9990000. Therefore, 0.8472195195195195... = 8463723 / 9990000, which, like the last one, can also be "simplified" to 2821241 / 3330000.... again, "simplified" is used very loosely.
I love when I hear people say they hate math or are terrified by it. To me that just means your teachers are bad at explaining or don’t know how to teach it. Math comprehension is completely related to the teacher. I had a teacher go through the proof of an equation and it completely confused the whole class. During break I went up to the board and erased the whole thing but the actual equation and in 2 mins said this part means this and this part means this. The whole class was sitting there dumbfounded realizing that the teacher wasted an hour on something that needed maybe 3 sentences to convey.
Respectfully, there's nothing easy about this. 😭
Well... its much easier than school
Thank you once again. Have you got an equation that turns back time?

Non-repeating decimals are irrational and a fraction can't be found for them

Any number that ends with

Your first example was way better, you not putting it into a fraction now in the other examples is confusing.!!

Divide the numerator by the denominator. 😊
Thank You Sir :) Keep Making these kind of videos. It helps a lot for solving Quant questions.
Do you have a video on how to convert a fraction to a decimal???
If you divide the numerator by the denominator you will get your decimal equivalent. 3 divided 4 =.75, 11 divide by 12 =0.9166666

3:05 is there a simple way to do mental division like this? You divided 1875 by 25 extremely quickly.
He probably already had the answer before he even wrote it down. Something off screen he probably did
There's something called calculator
@@meenumanzoor3141 yeah im pretty sure i know how fast it takes to put stuff into a calculator
Multiply 25 by 4 to get 100.
1800 consists of 18 hundreds
18 × 4
to mentally calculate this, double it twice. 18 -> 36 -> 72
there is still 75 left (1800 vs 1875). Add 3 that you get from 75/25
72 + 3 = 75
Great video. Extremely helpful.
thank you so much
Wow, awesome!!

It was a really helpful video. Can you do one on reading scale
A similar method is to do this:
0.732424242424
Take the total decimal pattern right up until you start repeating (including the repeated part), i.e. 7324
Then subtract the part that isn't repeated, i.e. 7324 - 73 = 7251
This is the numerator.
The denominator will be a number that has the same number of 9s as the repeated pattern's digits, followed by the same number of 0s as the non-repeated pattern's digits
The repeated pattern is 24 (two digits), and the non-repeated pattern is 73 (two digits), therefore, the denominator is 9900.
So, 0.73242424.... = 7251 / 9900, which can be "simplified" to 2417 / 3300 - of course I use the term "simplified" loosely.
And just to prove this wasn't a fluke, here's another example:
0.8472195195195195195195....
Take the decimal part up to, and including the repeated part, i.e. 8472195
Then subtract the non-repeated part, i.e. 8472195 - 8472 = 8463723 (this will be the numerator)
Now, we take the repeated part, which is 195, and put the same number of 9s as the number of digits in the repeated part, i.e. 999
Then we take the non-repeated part, which is 8472, and put the same number of 0s as there are digits in the non-repeated part, after the 999, to get 9990000.
Therefore, 0.8472195195195195... = 8463723 / 9990000, which, like the last one, can also be "simplified" to 2821241 / 3330000.... again, "simplified" is used very loosely.

sir the question no. 5 you made 15 into 1 since it is in 15's table but 90 comes 7 times in the 15s table
i hope this helped
