Felicity96:
I cant see it Bby
Allison:
Oooo uhm hold on.
Felicity96:
Dang it i know this
Allison:
I CAN'T THINK.
Allison:
Oh wait I think I got it. Square-root of 1/5 is 0.5. @Pixel is that rational or irrational?
Pixel:
rational it goes into 1/2
Pixel:
but what does 1/5 have to do with it
Allison:
Allison:
We can cross out the first one because it's rational like you said. And we're looking for irrational numbers.
Allison:
Now the second one, square-root of 1/16 is 0.0625. Rational or irrational?
Pixel:
rational
Allison:
Then we leave that one.
Allison:
Square-root of 1/10 is 0.1. Rational or irrational?
Pixel:
rational
Allison:
Right
Allison:
Square-root of 1/4 is 0.25 Rational or irrational?
Pixel:
rational
Allison:
Square-root of 1/8 is 0.125 Rational or irrational?
Pixel:
rational
Allison:
Hold on these are all rational. Is there a "Non of the above"? Lmao. Omg. @Vocaloid
Pixel:
nope

ObtuseAngle:
I got this ;o
ObtuseAngle:
So irrational means not expressible as a ratio of two integers, and having an infinite and nonrecurring expansion when expressed as a decimal
Allison:
._.
ObtuseAngle:
im not done e.e
ObtuseAngle:
1/2 means .5 so does that go on infinity?
Pixel:
nu
ObtuseAngle:
So it is rational
ObtuseAngle:
1/16= .0625 is it rational or irrational
Pixel:
rational
Pixel:
ive said this
ObtuseAngle:
1/10= .1
ObtuseAngle:
rational or irrational?
Pixel:
rational
ObtuseAngle:
wait thats odd, these all appear to be rational, one second
ObtuseAngle:
I double check and they are all rational? thats strange
Allison:
That's what I said.
ObtuseAngle:
oh wait, i think i know whats wrong one minute
ObtuseAngle:
@Pixel is that the entire question/all the answer choices
Pixel:
yehs
ObtuseAngle:
I suggest you email your teach and send a screenshot of it saying they are all rational
ObtuseAngle:
with the question the only answer would be to leave it blank, but k12 would mark it as wrong if you leave it blank
ObtuseAngle:
@JustSaiyan does this make any sense to you?
Pixel:
he goin to lunch

@HuskyNation
HuskyNation:
Okay so
HuskyNation:
An Irrational Number is a real number that cannot be written as a simple fraction.
ObtuseAngle:
They are all rational though
ObtuseAngle:
I checked myself then with 2 calculators
HuskyNation:
Wrong
HuskyNation:
A rational number is a simple fraction for example 1/2 = .5 that is ractional Irrational is 1/3 = 0.333333333333333333333334
HuskyNation:
So the first one is square root of 0.5 which is 0.707106781 making it irrational
Pixel:
;o ur so smert
HuskyNation:
See @Ultrilliam Math is my stronghold ;)
HuskyNation:
Putting 1/16 in the calculator is 0.0625 that is irrational BUT
HuskyNation:
the square root is 0.0625 is 0.25 So making the second one rational
Pixel:
so you divide then square it?
Pixel:
.1 squared?
HuskyNation:
Well i divided it to find the decimal for the fractions easier for meh
Pixel:
0.316227766
HuskyNation:
Correct, making the third one irrational
HuskyNation:
Now for the fourth it is .25
Pixel:
.25 = .05 rational
HuskyNation:
squared .5
HuskyNation:
it is actually 0.5 :D
Pixel:
sorry .5
HuskyNation:
so it is rational
Pixel:
.125 = .25
HuskyNation:
correct so that is rational
Pixel:
so it is those
HuskyNation:
So that means you only check the 1st and 3rd one
HuskyNation:
because those are the IRRATIONAL ones
Pixel:
otai tank oooo huskeh
HuskyNation:
Of Course :D
HuskyNation:
the other people had no idea what they were talking about XD
ObtuseAngle:
e.e
ObtuseAngle:
i used a calculator so :3
HuskyNation:
i did as well, lol idk the square roots of decimals like that XD
ObtuseAngle:
no i meant i entered in the fractions and it said they were all rational
HuskyNation:
yeah the factions them self all are but you have to do the square root of those fractions :P
ObtuseAngle:
ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh yeah
ObtuseAngle:
mb
HuskyNation:
