Adding Mixed Numbers

Missed the previous lesson?

Pre-Algebra on Khan Academy: No way, this isn't your run of the mill arithmetic. This is Pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We're about to take off!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

[faviolagonzalez]

learn you i had to re learn them after i forgot thank you

[globalenergy]

man you tell me everything that i don, t know

[nikoleyyy]

THIS IS MY SAVIOORR ~ THANK YOU ^____^

I always thought it would be 5 + 17 = 22, then have 1/9 + 2/9 = 3/9 (1/3). So it would be 22 1/3. So I guess I was right, after all.

[erikamurillo]

what do you do if your bottom number isnt the same? do you add them?

[jadalynquinonez]

what do you do at the end if one denominator is even and one is odd

[nriab]

How long is it generally until you post your videos onto you website? thnx

[epicblaze]

..I thought you had to find the GCF or something...Thanks!

[shesmycousin]

I have to watch this other whise my brother gonna spoil all of walking dead for me

kaitlyn dustin Saying it's stupid is just stupid. You had to learn it the same way you still have to learn how to add mixed numbers with different denominators (as you asked). Take a look at 1:20 in the video. For 5`3/8 + 9`1/2, you do the same: add the integers (5+9=14), then get the same denom' for 3/8 & 1/2. Well, their LCD is 8, so your 1/2 becomes 4/8, so 3/8 + 4/8 = 7/8. Put that back together with your added integers, you get 14`7/8. So there's your answer.

So I understand how to add mixed numbers, but I forgot what to do if the answer is an improper fraction.

[jinniedo]

but what if the question is 1whole # 3 over 4+2whole # 2 over 4 that is what I don't get about this work so ya please wright back

[kaitlyndustin]

this is stupid just about every one know how to do fractions with the same denominator i'm looking for something like 5and3/8 + 9and1/2=? yea something like that you know that's what I don't understand because I am not really good with fractions and other math relative stuff and im not very good at righting to but that does not matter so please right back
