In this lesson, you will learn what a proportion is, how to solve proportions, and how to calculate the value of a proportion. A ratio is the comparison between two numbers, and a proportion is when we set two ratios equal to one another. When we solve a proportion, we must learn how to solve an equation for the unknown variable. In this lesson, we describe what proportions are used for, how to set up a proportion as an equation, and how to use the concept of solving an equation to solve a proportion.

I am 55 years old and math has been my biggest weakness. I finally decided to tackle this weakness and found your channel. You are a God-sent blessing to me and to all those people who want to learn and progress. May God bless you with all the good things kind Sir!.
Okay, so I'm 45 and finding myself starting school from scratch to further my career. I used to be EXCELLENT at math in high school. I went up to calculus. Math feels so foreign to me, now.
The very first explanation you gave on what proportion is was SO GOOD. I'm going to explore this channel!
Hey Tina you are wonderful and keep it up It's fantastic no matter how old you are and always hope and progress out there wait for true mind people like you. Good job
I have brain damage...and I'm pretty good at math...usually, but your explanation here helped me reconnect to that part of my brain that was questioning my formula...Thanks!
Thanks so much, I'm continuing my son's education throughout the summer to cover areas missed from the pandemic's lack of continuity in education.
I love you....you're the best math teacher ever! I'm 68 and a total math phobic..
no words . simply the best
Thank you! You are explaining it very well.
I'm your avid follower in your tutorial. It's great very understandable. Thanks for everything. God bless
Love to watch so simple 💕
I'm your long time follower your such a great math tutorial instructor. I Learn a lot about math. Keep safe and god bless. Thanks
Thank your sir, very well explained, very easy to follow
Thankyou bigtime you are an amazing teacher!

Thanks...very well explained.
Thanks for your help 👍 it's really helpful you are the best 👌
Nothing more than thank you so much, you are amazing
Thanx for the hard work
great teacher, thank you
Thank you! It can be applied even to bigger numbers! I fully understood!!!
you are the best teacher in mathematics
Thanks a lot my new teacher. ❤❤❤👍
I really enjoyed your teaching
Thank you sooo much i have an exam next week and all the topics we had to study i forgot but when i saw you videos i rememberd everythng in just 1 day😁😁😁
I love the way you teach! Do you have more videos or do private zoom tutoring? I need help with word problems! Getting ready to take Hesi exams for nursing school
You’re the best teacher in UA-cam
I learn so much from you, thank you from South Africa
You are very welcome!

Please sir may you help us through Bending moment and shear force calculation, if you have the knowledge because that one is in Civil engineering
Wow thank you so much u made it so easy for me to finally understand ratio❤❤
Thanks for ur teaching 😁
Thank you for your teaching.
In the numbers rational propotions they can also be solved in this way
Ex: 3/5 =X/15
X=9 3/5
Molt 5X3=15
Molt 3X3=9
X=9
2EX : 1/2= X/6
2x3=6
3x1= 3
[X =3
Yup it's 9
Sir you Are so simply teach your teaching style so good
This is very good 👍 and grateful 👍👍👍👍👍
Thanks!
Thank you.
THANK YOU... SIR...!!!
Bro you just saved my life 😊
Glad to hear that!
Thank you I hope I will use this to get into 6th grade good school next year.
sir could you please tell me where i can see you electricity and magnetism full videos as in the playlist created the videos were cut and not full?
Perhaps check his website!
Thanks a lot Sir😇
Thank you so much, I have lived my whole life thinking I was unteachable in regard to math. Tried it at school and failed, tried it again in college and failed and so gave up. That was until now. Something just clicked by the way you teach. :0)
This is great
Thanks 😊
Hey Jason, question I am planning to study bio-chem and forensic science in university. Do you recommend, I take statistics in highschool? Or is pre-calc just fine? Thank you
I would do the pre-calculus and high school which will set you up for calculus in college. And then I would also take statistics in college which will definitely be required for your degree. Good luck on your studies! Jason
thank you sir
Great teaching skill thank you sir.
How you do x over 8 : 3 over For
Thank you so much...this video help me alot
Awesome!
Do u have an Instagram account...m about to appear a competitive exam...there are so many maths problem that i cant solve...maybe if u can help me....il be very happy
Thanks for edifiying stuff
I love this I should have watch your ratio first
Brilliant teaçher.
With this strategy what if the pronumeral was on the bottom?
Thanks.
Thank you I can do it own now.
Thanks
How to teach a kid to solve an equation if the variable is a denominator... Sir the way you talk out maths is amazing. Please help me out with the above
Good teaching, always straight to the point.
good teacher
It's easy tqvm
Great video ❤️🌹👍👍
Thanks so much!
Dats really looking good
Wouldn’t it be easier to cross multiple then divide to solve for unknown?
Sir I can't find electricity and magnetism in your math and science tutor app
I wanna join your class as a beginner please can you help i really understand you subject
Could you cross multiply to solve these problems?
Yes you could - however I don't like teaching it because cross multiplying hides what you are actually doing, and it is only applicable to this specific type of equation. What I am showing you here is "real" algebra and these skills will be used basically forever going forward solving more complex problems. I don't like "one off" solution techniques where you don't know why it works - here you understand exactly why every step works. Jason
Thank you very much!
At 10:00 W is 6
I can see it so clearly.
Unfortunately I never made it to algebra in school.
Fortunately I live in the youtube era, here I can learn.
You can also cross multiply to get the answer:
12 = 2w
Just divide...
w=6
I think convention to represent a proportion is
2:3::4:6.
Tomorrow I have a math test and I dint know what is ratio & proportion im watching your videos
What you know about rollin' down in the deep?
When your brain goes numb, you can call that mental freeze
When these people talk too much, put that shit in slow motion, yeah
I feel like an astronaut in the ocean, ayy

difference between directly proportional and propotional
Pls can you do 9th grade proportion
Hello Teacher,
Hi!
It's difficult maths but I trie to do practice
1/2 x w/12
GOOD GOD! Give me more!
Yeah!
I don't know if it works with all numbers but I say 4 goes into 12 3x.. 3x 3=9
Can I give you questions
3(12)/4
2/3 x y/9
Math is visual
1/4 x h/28
1/2=w/12
(3)15=45
Great
🤟🏿
Dios le bendiga y le cubra en el nombre de Jesús
X over 8 3 over four
🦄I LIKE YOUR WORK
36/4=9
9(2)=18
1/4=h/28
