Adding Fractions with Unlike Denominators - Part 1 (Fraction Addition)
More Lessons: www.MathAndScience.com
Twitter: / jasongibsonmath
In this lesson, we will learn the very important skill of adding fractions. In this case, we will add fractions that have unlike denominators, which means that the bottom numbers of the fractions are not the same. In order to add fractions, the denominator of both fractions must equal the same number. In these problems, the first step is to change the fractions by multiplying the numerator and denominator by the same number with the goal of expressing both fractions in terms of the same denominator. Then, we add the fractions as usual and simplify the result. Here we use fraction models to understand what it means to find a common denominator and to fully understand what it means to add fractions together.

There are many math teachers on KZread but when I'm doing a new topic and I don't know who to trust with my learning I come to your channel. Thank you sir.

Welcome!
I clicked on this because it looked scary. But... you simplified everything to make it very easy to learn. I wish I could give you a trophy for KZread TEACHER OF THE DECADE.🏆🏅🥇🎖
At 50 years old, I decided to take an IT course and because I don't have a college education, I need to take a basic skills assessment. To my dismay, I've learned it will include fractions and decimals! I haven't done math with fractions or decimals in ages! Thank you so much for making this as simple as possible!

Wow!!! You were born to do this. You are what I call a True teacher. Thank you.
You always have a great pattern of teaching math lessons that can easily be understood by students in elementary grade..Great job , sir..God bless..Students are learning from you well..God bless..

No don't do that
You’re a true teacher! If kids could learn math that way, many of them would love this subject. Math is amazing it depends who teaches you that. Thank you so much!
Although I don't need this kind of lessons myself, I strongly believe that your tutorials/instructional videos will make it into history. Your approach and ease of passing information to the viewer are highly valuable. I reckon that many people without access to quality education will grow to become better people (or engineers) with your help. Whoever's got some math or physics deficiencies, I recommend them your channel and the website. Please keep up the excellent work. By the way, thank you for the series on Laplace Transform.

*note: 6/9 is odd and even, but can still be simplified to 2/3. So when it is said that you can not simplify any further because one number is odd and the other is even, that might be a little confusing! Amazing video though! CLEAR visuals and reasoning. I love love love this!! ❤️

Great stuff! I wish I had those magnets back when I was a kid struggling with fractions. Question: what do you think of the "butterfly" method of adding fractions?
Wonderful amazing great video!!! I was very disappointed because I did not think in your first explanation what the problem, when converted, would look like in tenths! I thought I was going to have to visualize and conceptualize the changed fractions myself!!! AND, I really, really wanted to see what was really going on after you converted the original fraction! BUT, you HAVE Shown what really happens after you change the denominators (to all tenths)! SO, a BIG, THANK YOU, from me to you!!! And, it's actually more of a reason than what they look like.
If you think the same thing as me then we will all agree that he is the best teacher so you guys have to think about what you are going to say to him
Very informative thankyou!
All these years I couldn't figure out algebra. Maybe it was the long naps I took during 5th grade math. 😭

Very good teaching...I'm not an english native speaker but I got the whole idea.
I had never understood aboit fractions but now I do. Thank you very much
Thank you so you tought me a best fraction in my life may God bless you 🙏 for ever
I noticed that the common denominator is usually the larger denominator of the two fractions within the problem. And multiplying the smaller denominator of the two fractions by a number that makes it equivalent to the larger denominator to find the common, add, then simplify.
Thank you.

Liked very informative
Very good explanation
I like your video because it helps me in my work and test i think it can help my brother's
Usually, teachers will explain how to do the solutions but not answer WHY we did the solution. I am trying to have a good grip on Math and Chemistry fundamentals. I will be a college student soon, it embarrasses me that I am slow in both subjects, and I even chose a STEM course. I am afraid to be a laughing stock in college and decided to learn these things. Thank you so much. I am not excellent in math or science, but if I could learn English and Art on my own, maybe there is hope for me.
This really helped keep doing what you do!

Thank you from useful lessons. Can you please teach us about rounding decimals. Thank you
Sir what would be the answer of 2/8 + 2/9 ? The denominators are even and odd they haven't same multiples .. please sir

Make a denominator to 72. Multiply by 9 to 2/8 and multiply by 8 to 2/9 so 18/72+ 16/72=34/72

why we use 2x2 and 4x2 to make 4 by 8 in simplest form why we don't use 1+1+1+1 by 1+1+1+1+1+1+1+1 and cut similar one to make 4 by 8 in simplest form

I think LCM and LCD are the same except that LCM is more generally used and LCD is used with fractions, while adding fractions. Kids would have enjoyed your lesson, adding fractions. Even the adults could if they haven't done it earlier as I did it once. A story is to motivate A lesson is to teach An example is to inspire Time is to test.

@@mathsandsciencechannel I think of some shortcut methods to find LCD: 1. If the denominators of fractions are primes,just multiply them to get LCD. 2. If one denominator is divisible by another evenly,then dividend is the LCD. 3. List some multiples of larger denominator,divide those by another,the first multiple that divides enenly is the LCD.
