latest videos review of fraction decimal percent and how to change them from one to the other start with changing decimal to fraction this one is all about the place values different sense if I had zero .4 I look at the last number in the place value before that is in the tenths place value so I put the 4 / 10 however that's not the answer because you have to reduce by the greatest common factor someone to reduce bite to so that I get here to fix so the last number that tells me to place all you do and more let's say I had 2.15 with a the last number that is in the tenth hundred so tense hundredth hundredth place value someone put it over 100 in decimal part goes over the fraction the whole number the ones place value is the whole number  then once again Henry do the 15 and you good divide that by five I get two and three and we go 20th always reduce that you need to be a question anymore something on the last number this one was in the 10th this one was in the hundred that tells your place value and a number in front of the decimal is the whole number video to change fraction to decimal this one is all about division time do one example hear what they read 5/8  Bethel change volume for the whole numbers real estate 1 and 5/8 if you have an X number to change it into an improper just kind of a pattern we doing 7th grade so I'm going to say 8 * 1 + 5 if I get 13 and then I'm going to divide 8 into 13 now we're changing it to decimal this time so I'm going to add to I always add 3 if I don't need all three great if any more than three I probably need to read the instructions and say hey did they tell me to can I do with peanut tension or is there a pattern that I can just simply stop in the 13 is once the whole number whole number can bring it up monster it up that's remainder 5 Halo 5 we are technically if you keep adding kind of skip that step brand you can bring down your 06 x 48 bring on the next zero flights  Cameron on the next one perfect if it didn't stop I was stopping read instructions and clearly the hopefully they told me some weird around but there's mansur 1.625 so decimal to fraction place value fraction to decimal all about division  I was going to Funk the term of changing decimals to percents I'm going to give you lots of examples for the key on here is were going to move the decimal decimal to to the right so let's where is Battalion 0.9 may take the stuff Mall  number one wife to the next so what I have here is  nine and a 7-0 this is 90%  2.9 or you could have put a zero here moved to twice 90%  alright so we have next is 0.4 h move it to the right so I get 48%  that's how I write my percent sign so you'll get used to it on on how about 0.05 to the right to the right this time we get zero five four seven what you can just ride at 5% Let's do an even bigger that's Muhammad 002 play the lake at 7 how about that  so once again to the right no matter what no matter what two to the right this time is .27 and then put your % so .00 to 7 really makes 27% and yes you can put a zero in front probably the preferred method how about 5 to put a whole number this time in front nine sex and this is 598.6% so sometimes I take decimals you get rid of decimals altogether other times you still have decimals in there change fraction to percent this all happens to be divided so you can get a decimal and then follow the exact same thing to the right the really any time trying to change a fraction to a percent the easiest way to change it to a decimal and move it there are other ways to change it to a but I find this way works every single time in the other one only work partially so I'm going to only do it this method  Sir Francis list had seven Knights  I'm going to divide 9 into 7 in the real like I said I'm going to have three spots I need more than I should probably see if I needed around earlier Salina 702-092-7763 reminder 7 again this here to Round right now I really want you to go through numbers out even if there's a pattern the reason for this is when this keeps going if you don't write at least three numbers out then we have to Arsenal twice so if you accidentally just put here and stop your going to have a really hard time changing it to a percent so please do not do that laughter is 0.777... should I get 77.7... And now and by the way the percent sign that looks hideous right 7.7% sign that's now where we put the bar so this is 77.7 with line over the decimal part percent or some people even around right here that's a 77.8% either one of the is would be correct  but do not put the bar over it up here that's where you're going to get yourself into trouble keep going until you've done the very last day then to the bar or then round  what what's going to the next category  laugh percent decimal percent to fraction  at the start of the percent to decimal this one is the exact opposite of the other one this one is two to the left of the opposite direction  the princess left I gave you a hundred fifty percent  the first of all there is no decimal in here what we got to do is got to put it in here the only place I can put a decimal that wouldn't change this number as at the very the hundred 15% or 115% is the exact same thing so there's no decimal just for that the end and I were him set to the light someone to So my answer here now is one 1 V with no percent  make noise check at the off the way if I move it to the right what I come up with that answer and yes it's remarkable. 48% don't know decimal, put it in move it to the left planned up with Point 48 and you can always put a zero on if you like but Strathmore one 3%  put the decimal in  leave at 1 to 4 this time we're going to have what is 0 in  so this is .03  and you can always add just like I said here at the extra zero before the decimal Emmett actually have one with enough morning how about 2.5% to this time it has a decimal so really all I have to do is instead of adding us more like we did here I just used the decimal up in it and then move it to the left so that already has a decimal in the problem just use that and move it to the left if it doesn't add one at the very end and then move it 10% fraction when you're changing percent fraction everything always goes over 100 every single time over one no matter what the number is  so 18% really is 18 over 100 and obviously can have anymore you need to read it is at 2 so 2:18 is 9 and that is Mary up 9:50 how about 5% anything over percent to fractions over 100 5 over 100 cuz nothing to do with place values that's fraction decimal percent and fraction is always over 100 to reduce leave by 5 + 1 + 20 - 1/20 just took a really big one how up 436% once again does not matter it's always over 100 436 over 100 reduced its easier try this first on the 5th floor and 36 over 100 easier to reduce this later which then finally gets me for and 136 living makeup is a for so foreign to that is 9 and 4 into the hundred is 25  now you can discounts for the decimal and percent to fraction but I'm probably going to talk about that later this year I seriously doubt if you talk about that in 6th grade if you want to preview here you go so 2.5 over hundred can't have a decimal in a fraction so I got to get rid of it from the X place value  I guess I'll talk bugs and detail later but if you want to preview 10 * 2.5 is 25 over a thousand divided by 25 and I get 140th  Meredith but don't worry about that one will definitely practice it all the other ones you really should know how to do by now if you need to look at any of the other videos please Penelope homeschool on in August
