- How does 1/10 have to seam value as 2/20?(4 votes)
- They are equivalent fractions. Since when you multiply 2 in both the numerator and denominator to 1/10 it gives you 2/20 OR if you divide 2 in both the numerator and denominator of 2/20 you get 1/10. If you multiply or divide in both the numerator and denominator, it does not change the fraction.

- does it just keep going the number and then "ths" like ten-ths, hundre-ths? does that mean it would say millionths(2 votes)
- So, technically VolcikShotKill is correct because you could be like ones, tenths, hundredths, thousandths, ten thousandths, hundred thousandths ect. ect.(1 vote)

- How do you do you order those numbers? I found it to confusing.(0 votes)
- It helps if you look at the numbers directly to the right of the decimal and see which ones are greater. Then move farther right. Like 0.45 and 0.23. The four and two are closest to the decimal so if you compare them you can find out which one is greater. 4 is bigger than 2 so 0.45 is bigger. If two numbers are the same move farther to the right.(1 vote)

- you make look so hard and it is I'm in 5th grade and this is so confusing can you make it more...... look easy and pls do one about what a whole number is.(2 votes)
- thanks this was very helpful😀(2 votes)
- it says i have no assignments(2 votes)
- Which is the largest number between 0.098, 0.145 and 0.109(1 vote)
- Yup, what they said. Another way is to just look at which decimal has a number in the hundredths place, then look at the numbers behind it(1 vote)

- I don't never understand this help me?(2 votes)
- can someone help me understand this video(1 vote)
- Sure, Zachary! So what he is trying to say is that the you can just compare the numbers once u line them up in a place value and compare them! (U can use the way he did it! My preferred method!)

## Video transcript

Let's once again see
if we can order now a different set of decimals
from least to greatest, and once again I encourage
you to pause this video and try to do this on your own. So let's go to the most
significant place, the ones place here. None of these have any ones. So then we can go to the
next most significant place, which is the tenths place. This has five tenths. This has six tenths. This has one tenth. This has five tenths. This has one tenth. So if we just look at the
tenths place, the ones that have the fewest tenths--
this has only one tenth, this one only has one tenth,
this one has five tenths, this one has five tenths, and
then this one has six tenths. So I've ordered it by what's
going on in the tenths place. Now, both of these have
the same number of tenths. Let's move to the
hundredths place to figure out which
of these is larger. This one has six hundredths. This has five hundredths,
so this one is larger. It has more hundredths. Same number of tenths,
more hundredths. And hundredths
are obviously more significant than
thousandths, so it doesn't matter which one
has the more thousandths. It matters that this
one has more tenths, and actually this one has
more thousandths as well. But now let's go
look at these two. These have the same
number of tenths. They both have five tenths. But this one has six
hundredths, while this one only has two hundredths,
so this one is larger. And then finally,
this one of course, had six tenths, so this
one had the most tenths. So we don't even have to look
at the other places here. And we're done.
