One and a half is a whole plus half of the whole. The whole in this equation was 200.

No, one and a half is precisely that. One and a half. As in the number between one and two.

One and a half is 1.5

 

[Dis86]

One and a half is 1.5

Correct. It's not 300.

 

[dlockers]

Correct. It's not 300.

It is if the 1 is 200 and the half is 100. The only given number of the first part of the equation is the whole.

1 could be a basket of grain, and half a basket of grain would be equal to 1 half a basket.

You are substituting 'half of' with a number you've decided, just like I did with 50% instead of 0.5.

But that's the point. The question doesn't say half of. It says half. As in 0.5.

It says reduce by half in the context of the given value.

 

[Dis86]

It says reduce by half in the context of the given value.

It doesn't say that at all. Reducing by half would be, by your own logic above, 199.5

How much should you expect to pay for an item in a shop if you are told the price of the item is "half"?

I would insist on a 50 pence discount because relativity and context is not a thing. We all know half off is 0.5p off.

£500k.

This is one if those retarded viral questions you see pop up on social media every now and then, slightly ambiguous with the 'by half' element.

 

[Zefan]

This is incorrect.

Original odds were 1/3.

As a cup with no gold in was removed you have to recalculate the original odds since hes told a cup with no gold in was removed.

The chance he picked the correct one was ion fact 1/2 and is now still 1/2.

You cannot have odds less than 100/100.

Aren't you just rewording the post you're disagreeing with here?

You have a better chance of winning (2/3 instead of 1/3) if you swap.

pfff

Correct. It's not 300.

This is 300......

HALF THE POPULATION

i.e. 0.5 of a person

Am i rite?

 

[Dis86]

HALF THE POPULATION

i.e. 0.5 of a person

Am i rite?

No. Because a singular person isn't the population unless the population size is 1.

How much should you expect to pay for an item in a shop if you are told the price of the item is "half"?

I am not half a shop?

 

[dlockers]

No. Because a singular person isn't the population unless the population size is 1.

Ahh I guess you are finding peace when they discover its "half size" and you just subtract 0.5mm
