Math.   >:(

Long rant typed up, and....never mind.  I'll speak to a teacher.

How the *fudge* does something times something equal less?

1/2 * 1/2 = 1/4?  Doesn't "times"/ multiply mean "make more"?  See:  Rabbits.   
How the *fudge* can I start with half a *fudge*in' pizza and [sarcasm]multiply[/sarcasm] and end up with less *fudge*in' pizza than I started? 

Oh, gets better!  Let's divide it!  I start with 1/2 a pizza and the next thing you know,  I'm farkin' Heyzoos with loafs and fishes!  Bam!  Whole.

*Karma for the reference.

This made me feel better:

That made me feel better too.  That kicks ass!

I wanted to see it bounce.

Maybe this helps:
1/2 x 1/2 = 1/4
.5 x .5 = .25

Or you can just press the "I believe" button, crack open a cold one, and say "what the *fudge* does this have to do with real estate?"

In the realm of arithmetic on the set of real numbers,  multiplication is simply {repeated} addition.    There is an implied zero in your bolded,  add  one half , of your half to zero.  1/4.  That is the concept, #s aside.   Just as 3*(1/2)=1.5   ( Add 3 1/2's to 0 ....)

Why would adding my half to my other half work towards zero, as opposed to one?

<----------------------------------->
             0  1/4    1/2     3/4     1

Re-read what I said,   you aren't adding the 1/2 (or anything therein) !to the 1/2! .  You're adding 1/2 OF the 1/2 to Zero.   When you do 3*3,  are you adding 3*3 (3+3+3) to an (initial) 3?   no, you would get 12 then.....  When you do 3*2, are you adding it to an initial 3?  no.  think how 3*1 and 3*0  work... you get the idea....  right ?   just because you've moved off the integers into fractions, the idea is the same. 

Holy *feces*, I understand the concept but you just lost me.

I did, about 14 times.   :sad3:

I get that.

   

That kinda makes sense.


I've spent so much time explaining fractions......Oy.

I'd rather explain "Suck my *8==>*."

I guess there's no hope of explaining division as repeated subtraction then....    [sm_devil]

LMFAO

Hahahaha

Day At The Park:  Le Film Noir per stroh.

Scene [1]:  Exterior. Day.  Pleasant day at the park.  A large crowd has formed around a grey bearded man.  The crowd is showing great excitement.

Scene [2]  Exterior.  Day.  The crowd gasps, and applauds as a large explosion booms, an a massive smoke ring rises above the grey bearded man.

Scene [3] Exterior.  Day. Children rush towards the center of the park.

Scene [4]  Exterior  Day. 2 hours later.   Introduce man, late 40's, stoic, known as:  County Forensics investigator.

Scene [5]  Exterior Day.  A child lay lifeless, apparently with head crushed from an anvil falling from some height.

I watched that dude on the History Channel.  (Might have been Discovery)

You're all insane...

Ah, just wait.  You'll be there soon Brotha*.



*Speakin' of which, where Seamus be at and *feces*?  (Again)

Prolly looking up some guys ass crack as we speak. "Ok boys spread em".  [sm_shock] [sm_disgust]
Least he's got a job.  :D

I thought aske's explanation was spot on.  That's one way to remember.  Another is .5 x .5 = .25

But the easiest *goshdarn* way is to just multiply the stupid fraction.

1     1        (what the *fudge* is 1*1?  1 duh)  1
-  x  -    =                                             -   
2     2        (what's 2*2, *goshdarn* 4 moron)  4

That's your answer same way 1/2 / 1/2 becomes 1/2 * 2/1 and = 2

In your pizza scenario you have half a zaa with 6 slices.  Multiply it a half of a pizza by another half.  6/12 * 6/12  =  1/4  Math isn't jesus so halfing a half makes a quarter.  Jebus.

The issue wasn't how to do it.  This issue is trying to explain the logic to an 11 year old, how multiplying the fraction leaves you with something smaller than what you started with.

1/2 actually means "1 divided by 2".

Even though it's treated as a single number in your problem, it's really an operation of two numbers. Therefore, the original problem:

1/2 x 1/2  (half times half)

Is actually:

1 / 2 x 1 / 2   (1 divided by 2 times 1 divided by 2)

Which can be reorganized as:

1 x 1 / 2 / 2  (1 times 1 divided by 2 divided by 2)

Try it with this:

3/4 x 3/4

The ruler in our house shows that 9/16 is less than 3/4.  Unless I'm holding it upside down.

Sure. If you multiply something by 3 and then divide by 4, you get a smaller number than what you started with.

Is anybody actually reading what I'm writing?



I think I can explain this in a way she'll understand.

OK I was in the just do it this way mode and you'll figure out why later.  That's how I was taught.  But gleek's explanation is much better as to the why.

You could always try it with the distributive property


(1/2)*(1/2)=(3/2-2/2)*(1/2) =(3/2)*(1/2)-(2/2)*(1/2)

simplest explanation yet

Well, I was stupiefied long before getting to this point.   Finished the thread with Blader's last post and I seriously hope he was saying this in jest cause by then I was well beyond stupified.  ???  ::)  :o  ;D

I'm not jesting.

I've long held that if Aske were to only speak in calculations and equations, he'd be far more understandable.  See my collected works, now available on amazon.

Not that anyone cares, but 1/2 / 1/2  becomes 1/2 * 2/1 which = 1 not 2................

Yeah right I was ranting with little to no fact checking.

Uh huh huh huh. He said "conjugation". Uh huh huh huh...
