sir time:51:04 How to make three equal parts there in number line
I'm also not understand this number line system?
51:04
Maybe because the denominator of the fractions is 3?
You have to just devide it into three parts you can use compass or scale to do that and you have to divide that with denominator in this example sir has done with 3 if it was 6/2 so you have to divide the number line into two parts
Yes sir
Finally i am in class 9 i am very happy and your explain and explain of your team magnate brains is amazing,great and this platform help for every children thank you so much sir

Sir 1:01:56 when you said that answer is -7/4 , -6/4 , -5/4 . In that part can't we write other numbers rather then these which lies between -8/4 and 20/4

I HAVE A QUESTION THAT I AM LEARNING MATHS FROM YOUR WEBSITE (MATHS OF CLASS 9TH) THERE ARE TWO PLAYLIST ONE IS OF RD SHARMA AND 2ND IS OF NCERT, ARE BOTH SAME AND JUST TEACHERS ARE DIFFERENT, OR THERE IS A DIFFERENCE?
Hi there! It's great to hear that you are learning Maths from our website. The two playlists are indeed different, as one is from RD Sharma and the other from NCERT. RD Sharma is a book for more advanced Maths topics, while NCERT is a book for basic Maths topics. We hope this helps!
@@MagnetBrainsEducation IF I LEARN FROM RD SHARMA SO THIS MEANS I WILL HAVE KNOWLEDGE OF RD SHARMA AS WELL AS NCERT BOOK, RIGHT?

Thank you for watching our video and taking the time to leave us a comment! We are glad that the video was helpful to you. We strive to offer engaging, educational videos to students, so we appreciate your feedback.
Dear @MagnetBrains,
Sir in Example 2 (48:48) can we cancel all those numbers. Like: 7/6, 8/6, 9/6, 10/6, 11/6
Please reply @MagnetBrains
Regards.
Thank you so much for your question! In Example 2, we cancel the numbers because we are trying to find the lowest common denominator. If we cancel the numbers, it will be easier for us to find the lowest common denominator.
@@MagnetBrainsEducation Thank You!

at 8:07 the decimal 2.5 is a terminating decimal or it can be written in the form of p/q as -5/2 its decimal expansion is 2.5😀😀😀
Sir if the number of denominator in negative then it will be the rational number or not
Yes

I did not understand the method you used in Q--Find 5 rational numbers between 1 and 2
It's very easy
Agar 5 ratonal number nikalne h to 5+1=6,ab 1 me 6 se divide aur multiple tb ayega 6/6 isi tarah 2me 6 se divide aur multiple tb ayega 12/6 ok. 6/6 aur 12/6 ke beech me 7/6,8/6,9/6,10/6,11/6
52:14 ...Represent 5 by 3 and -5/3 on a number line I can't understand this one can you plz help me sir
If I want to find five rational no between 5 and 6 then I have to divide it with 2 or other number
Sir apka teaching system 😎 acha hai

Sir you have told 2 methods to find out rational numbers between them but both get different answers .So how can we got to know that which answer is correct

Sir , example 2 ke 2 methods hai ............and if a question comes of 5 marks the which method should we apply ?
2024 me kon kon dekh rahe ho ❤❤
Me
thankun for replying to my other question but i have some other questions which mim really confused in if u can answer them kindly check the replies
🍓
sir one question: is every rational number a whole number?
Thank you for your question! The answer is no, not every rational number is a whole number. Rational numbers are numbers that can be written as a fraction, where the numerator and denominator are both integers (whole numbers). Whole numbers are integers that are greater than 0, so not all rational numbers are whole numbers.
Sir I had kept 5/4 at the second dash from begginning. Is it right?(method 1)( time 39:32)
Agar aap 8/5 ko first point pr likhoge toh 8/8 (which is equal to 1 ) kahaa likhoge
Thank u sir for a great explanation 👍

Hello
Bhai jo 26.3.24 ko dheak raha ha vo like kar da
Hii Guys so i have a question
1 Take offline classes of any institute
2. Take online classes like on UA-cam
What your opinion???
Sir, what if there's a question that says:
Find five rational numbers between
3/5 and 4/3 ?
So,in this problem we observe that the denominators are not the same.
Make the denominators same by taking LCM and then follow the same procedure.
Hope it helps :)
Find their LCM
First do the denominator same
