what is 5/6 +5 -4/8= i am lost with that
yes it is
ok so first let's try reducing the individual parts, e.g. -4/8 = -1/2
so now you want to find the lowest common denominator for 5/6, 5, and -1/2
to me that looks like 6
so now you want to convert everything to sixths so you can add them up
so 5/6 is done
5 = 5*6/6 = 30/6
and -1/2 = -1/2 * 3/3 = -3/6
so now let's add it up: 5/6 +30/6 -3/6 = (5+30-3)/6 = 32/6
now you want to reduce that fraction, so again we need a common divider
looks like the only common divisor is 2
so 32/6 = 16/3
now if you want to , you can change that into a mixed fraction
so 16/3 = 15/3 + 1/3 = 5 and 1/3
ok i am back
hey! wb
did that make sense?
srry my cumputer is giving me problemes agine yes it did thanx
ok great =)
the basic point is, anything x 1 = the same thing
so you can always multiple by various forms of 1 to get a common denominator
ok
so in the above, since I decided we needed a 6 on the bottom of all the fractions (common denominator), I multiplied 5 by 6/6 , and -1/2 by 3/3
to get 30/6 and -3/6
to reduce fractions, you're still essentially multiplying by 1
so to reduce 32/6, I divided both the top and bottom by 2
how dothen do u flip it
sorry then do u flip it
so how do you mean flip it
reducing fractions is still multiplying (or dividing if you will) by 1
just you're making the numbers smaller instead of bigger
32 is on top then 6 is on the bottem you flip it to were the 6 is on top and the 32 is on the bottem
in reality, it's easiest to think "if I divide both the top and bottom of the fraction by the same thing, it will still be equivalent"
oh ok that make senc
i am not good at math
it's ok, nobody starts out good at math. takes lots of practice and not giving up on it
so let's do another example: reduce 48/12
ok
your thought process should be: "what is the biggest number that evenly divides into both the top and the bottom"
and then do that
and it's ok if you don't know off the top of your head what the biggest number is
that also comes with practice
but you at least know in the above case, since bot the top and bottom are even, you can divide both of them by 2
so go ahead and try to reduce 48/12
I'll do a first step
48/12 = (48/2) / (12/2) = 24/6. I know that's true because I divided by 2/2, which is 1, and anyting divided by 1 = itself
ok that is what i got to
ok, now the next question you should ask yourself is if there is another number you can divide 24/6 by to get a smaller fraction - by smaller I mean smaller numbers on the top and bottom
that process is called reducing
i am geting so made at my comeputer right know
if i log out agine i will get back on ok it is my computer
ok np
we can divide 2 in to 24 and 6
oh nvm not six
and if it seems i am not i am i just in a livsseion i go to flvs
but i will tell you be for i go tho ok
kk, well you were actually right - you *can* divide both 24 and 6 by 6 =)
so I would do that
it would come ou to be 4/1
i think not sure tho
you're right =) . and 4/1 is actually 4
good work =)
so how would you check to see if you're right?
an easy way to check is with a calculator
is 48/12 = 4/1 = 4?
ok thanx you vary much
no problem!
so just remember - you can always multiply the top and the bottom by the same thing, to get an equivalent fraction. that's useful for getting a common denominator to make adding/subtracting fractions easier
and that's because you're *Actually* just multiplying by 1
ok the way my techer did it was confusing
and anything times 1 is the same exact thing, just written in a different way
now when you're "reducing" fractions, all you're trying to do is get the top and bottom numbers as small as possible
for that, you can always divide both the top and bottom by the same thing, to get an equivalent fraction
know with that rule does it count with 0 to
since in reality, you're just dividing tat number by 1
and anything divided by 1 is the same thing, just written in a different way
well, you can't divide by 0
or else the world explodes =)
ok @};-
is open study only for math
that I know of
well, I think there's another UI they have
but that's over at openstudy.com, and I don't think the logins are shared
I like this one more
ok i think it should make it for all subjegs but i guess it dos not relly matter tho
what else are you taking?
i am taking teck math langue arts chess and on the side i am lourning chines japens spanish french
i mean tech for cumputers
nehow
means hello in chines
2 to 4 i have a chess compition
oh awesome =)
that's a lot!
yea but in reality i should lour alot more cuz i mean i am not big on politics but ii do know alot about how most school seystem r laking on some eguoction
my friend is in 8th he deos not know anthing but it is also the pareints to not all on the schools
the schools can only teach so much in won day and they can not stay on won topec for long
i am not going to lie i use to be won of thos kide who were like when am i ever going to use any of this stuff but in reality u use it all the time
even if you relis it or not
