- At0:44, she mentioned one tenth, is there such a thing as an "oneth place" in decimals?(11 votes)
- Lindsay probably said oneth ACCIDENTALLY instead of ones but i'm pretty sure that she said one tenth(5 votes)

- 5/2 is greater than 5/6 am i right?(12 votes)
- Yep. 5 is larger than 2, but smaller than six.(1 vote)

- Ur a smarty I dumb how do math.(4 votes)
- Don't be disheartened, everyone struggles at maths once in their life.(14 votes)

- Oh no! Dude take care ! I hope you are alright!(5 votes)

- Can a decimal like 1.08 be converted into a fraction like 1 8/100(5 votes)
- Yes! And 1.08 IS 1 8/100 when converted to a mixed number. It is 108/100 when converted to an improper fraction.

If you want to learn more about converting decimals into fractions, go to this link, which is part of a whole Khan Academy section on converting decimals to fractions:

- so this is kinda confusing to me but im sure ill understand it in a while but can i get some tips and/or pointers(5 votes)
- I don't know if they categorize this new edition of lessons here on purpose or they didn't noticed they messed up but I'll say 'Isn't this concept a bit too late to taught while I just finished adding, subtracting, multiplying fractions. Now you're teaching me identifying tenths?' That's why sometimes I'm having a hard time on this new learning curve, it's either advanced or late.(3 votes)
- Yes, this lesson is here on purpose. It is showing how to find decimals on a number line. And, it ties concepts learned from fractions to the lessons on decimals. This is important because many decimals are just fractions in a different form.

The lessons on fractions had similar lessons that show how fractions relate to a number line.(5 votes)

- idk i just felt like it(5 votes)
- If the number line had 100 tick marks would it be 3.03?(4 votes)
- what is the piont of a decimal if you can use fraction?(3 votes)
- Because fractions would appear a bit complicated than decimals but the main reason is that we can easily see how many wholes are there and how many parts. for example - 7856/100 vs 78.56 we can see that the second one looks pleasing and it also tells us that there are 78 wholes and 56 out of 1 whole.(2 votes)

## Video transcript

- [Voiceover] Where is the
point on the number line? Well, here it is, here is the point. But I'm guessing that
they're asking not literally just to find it and look at it but what number is this point graphed at. Where is this on the number line? So, one thing we know pretty quickly is the number is between three and four. It's greater than three
but it's not quite four. But to figure out how
much greater than three we need to know what these
black tick marks represent. So, between three and four there is one, two, three, four, five, six, seven, eight, nine, ten equal spaces. So, each of these distances, each of these equal spaces, is one tenth or one tenth of the distance
between three and four. It's one out of ten equal spaces. So, if that's one tenth and this next space is another one tenth. And then we have to travel one more tenth to get to our point. So, we went three, we know it's three. Plus, one, two, three tenths. Three and three tenths. Or, let's write this as a decimal, let's look at it as a decimal. If we wanted, we could
have our ones place value and then after the ones,
the decimal and the tenths. So, for the ones, there's three ones. And how many tenths did we see here? There were three tenths. So, either way we can say
three and three tenths or three and three tenths. Our decimal, our point is 3.3 on the number line.
