what we're gonna do in this video is do a few examples ordering numbers that involve decimals so let's say that we had the numbers one point zero zero one zero point one one three and one point one zero one what I would like you to do is order these numbers from least to greatest take out some paper and try to do it on your own before we do it together all right now let's do it together and the way I would tackle ordering numbers is I would go to the largest place value that the numbers have in common and so in this situation we have a ones place value in all of them and so we could see that this has one one this has zero ones and this one has one one so the thing that has the least ones is going to be the smallest of the numbers so this one over here is going to be the smallest of the number so let me just write that over here zero point 1 1 3 and now we have to figure out which one is next between one point zero zero one and one point one zero one well then we just go to the next place value so we go to to the tenths place and we see right over here they're equal on the ones place so if you go to the tenths place this one has zero tenths well this one has one tenth so the number on the right here is going to be larger it has more tents same number of ones but it has more tents it doesn't really matter what happens to the right of that so the next smallest number if we're ordering from least to greatest is going to be one point zero zero one and then last but not least would be this one that is the largest one point one zero one let's do another example let's say we had the numbers zero point four two four zero point three four three and zero point four four three pause this video and try to order these from least to greatest on your own and once again the idea here is always start with the largest place value and then compare and then keep moving to the right if some things are equal all right now let's do this together so they all have zero ones so they're all equal there so that's not going to tell us much so now let's go to the tenths place so here I have four tenths here I have three tenths here I have four tenths so I don't you have to look at the hundredths or the thousands place this one has the least tenths so I can put that as the least or the smallest of the three numbers is 0.34 three and now so I've already used that one and so I need to compare these two numbers they have the same number of ones they have the same number of tenths so then we move to the hundredths so here I have two hundredths here I have four hundredths this one has less hundredths than this one so the one on the left is going to be the next smallest number so then we have zero point four two four and then last but not least this one right over here it has the same number of ones as everything else it has more tense than this middle one and the same number of tenths as the left one but then it has but then it also has more hundredths than the left one right over here so this is the largest of the numbers zero point four four three and we're done
