Let’s see if we can

write 0.15 as a fraction. So the important

thing here is to look at what place these

digits are in. So this 1 right over here,

this is in the tenths place, so you could view

that as 1 times 1/10. This 5 right over here is

in the hundredths place, so you could view

that as 5 times 1/100. So if I were to rewrite

this, I can rewrite this as the sum of– this 1

represents 1 times 1/10, so that would literally

be 1/10 plus– and this 5 represents

5 times 1/100, so it would be plus 5/100. And if we want to

add them up, we want to find a

common denominator. The common denominator is 100. Both 10 and– the

least common multiple. 100 is a multiple

of both 10 and 100. So we can rewrite this

as something over 100 plus something over 100. This isn’t going to change. This was already 5/100. If we multiply the

denominator here by 10– that’s what we did;

we multiplied it by 10– then we’re going to have to

multiply this numerator by 10. And so this is the

same thing as 10/100. And now we’re ready to add. This is the same thing

as– 10 plus 5 is 15/100. And you could have done that

a little bit quicker just by inspecting this. You would say, look, my

smallest place right over here is in the hundredths place. Instead of calling this

1/10, I could call this literally 10/100. Or I could say this

whole thing is 15/100. And now if I want to reduce

this to lowest terms, we can– let’s see, both the

numerator and the denominator are divisible by 5. So let’s divide them both by 5. And so the numerator,

15 divided by 5, is 3. The denominator, 100

divided by 5, is 20. And that’s about as

simplified as we can get.

thanks! ๐

Thanks! Can you do a video about applications of differentiation? Specifically with respect to applied Maximum and Minimum Problems? Thank you

Wow I never thought of it that way ๐

Thanks man, YOUR AMAZING!

What kind of sorcery is this you are a magician

thanks you helped me out about please make more videos like this i will like ๐

It makes sense now! Mr. Khan, you are a MIRACLE WORKER ๐

I didn't understand it

How do you do: .00000987234 I had this problem the last time I did a GED test and I was clueless and didn't understand what to do when it just said do these numbers. There were about ten different ones of this style on the test.

I still don't get it ๐

This helped me a lot thanks ๐

wow thanks it helps alot .my math advanced class is doing this I understood already….

Thanks for the help

yay 100 on math homework thx a bunch :0

this really help's a lot i was so confused before seeing this

Thanks for the help, this helps me alot

now that i look at it strat it a good problom

why am i watching this?

i dont even know place value anymore /:

this was very helpful

thank so much do you tutor

couldn't you have gotten 1/4 if you were to simplify again by 3?

i want u as my teacher, ill pay my soul ๐

I wish he was my teacher

What!? I am in spirit of math but I don't get it

this help me so much thanks ๐

Thank u

wow great video!!!!!!

0.15= 15/100= 3/20=150/1000……………………………… UNDERSTOOD!

Cool

?

I hate math ???????

Why are others disliking this video I mean what's wrong with this video he's teaching people mathematics

F…

I cannot understand!

I don't get it can they slow down and explain WHY they are doing it

thankmyou

thank you

I don't understand. Another example plse

I had the same problem for my homework ??

i thought this would help me on my math quiz for a grade.

i plan to fail now.

It's soooooo complicated to comprehend this

Ohh! I was embarrassed to ask my math teacher this because right now I have 101.25 as an average ?

Thanks for making this video ?

when you don't understand it and you look at every video and finally u understand it

im doing my test and i think i got an F ?

Thanks really helpful ๐

Thank you for this

THX!!!!!!!

thanks for the help

thx I couldn't call my teacher so…GOOGLE

good

Why we are multiplying 10 with the numerator and denominator

thanks for the help:D????

can you skip the multiplying and just do the adding?

Dude can u make a video about the concepts of transversal lines

-you don't really make things clear

wait i dont understand so since 100 is bigger than 10 its the common denominator???

Did anyone's teacher show them these videos in 5th? I did. If yes then maybe we went to the same elementary.

It is not a easy way to explain

What if a I have a whole number? It's 2.66

Slow it down man I mean, A LITTLE SLOWER NOT SYFFSBFSGSVSGGSBSBSNdbbehjejebsbhsjdnsbsksk

Are you a teacher? I needed this… Cuz im gr4 and i have a test thats coming up and im having trouble but your making it simple thank you!!!

MATH mental abuse to humans

Best teacher for math goes to khan academy good teaching to school students thank you khan academy

There hss to be a simpler explanation..

i had the same problem

Omg thank. You know I can prove my teacher that I'm not stupid

You make it sound so difficult

Thanks Salman!

this is actually really useful for converting some of the harder fractions atleast for me it is

I have a test on decimals to fractions that I need to know I and thought since it's tommorow this would help but, it seems easier that i just memorize it as the teacher said to do in the first place. When he teaches that and if i dont understand I'll come back.

thanks khan academy

Made this hard asf for no reason. Just put 15/100 and divide both 15 and 100 by 5. Since the last number (5) is in the 100th place you know itโll be over 100. And youโll get 3/20 the same way

A lot of people say they are still having trouble getting it. The trick is to watch multiple explanations of one mathematical concept. So watch different explanations of how to convert decimals to fractions. Because one person may explain it in a way you kind of understand, but multiple people will explain it in many ways that you will understand it all.

For those who do not understand. If you have 0.1 as a fraction that is 1/10 if you have 0.25 that will be 25/100 if you have 0.325 that would be 325/1000. Notice the pattern: for every digit you have after 0, that is how many 0's you will add to the 1 as the denominator. Dont forget to simplify the fractions as low as possible.

I get it

Love your videos โโโโโโ

If you do not understand put Math Antics converting decimals to fractions

mathantics

5th grade

help meWhy does he keep the 5 over 100 the second time?

LOVE YOU!

Understand hitches

?

0:53 ???

Who else is using this for homweork?

Nobody does this like my teacher?

Pre algebra??!?!? Boi Iโm 6th grade

COOOL

LETS GOOOOOO

Thank you I get it now I was so happy till I scream but since I am sick so I canโt very scream(thank you very much)

Everyone getting addicted to word, SO.

CANT UNDERSTAND ANY THING

Thank you ! (๏พโใฎโ)๏พ*.โง
