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
