Is it true that 0.999.... = 1?

Stupid question. Does $999 dollars equal $1,000. Nooooo!!

No, 1=1. Rounding a number up does not change the actual value of that number.

I concur, .999 is rounded off to 1 in my daily life, but it not actually 1.

They could string out 9's forever,and it would still not equal 1.

This one is wrong. 1 is 1. 0.999 is 0.999. It is as simple as that.

Your answer is WRONG!!

I thought these questions were rated before they could come on here.

Please report this BS question using the button on the top right. I try to get questions published with limited success and something like this gets through the review process???

Wrong! Just like the soap that claims to be 99.9 percent pure still has a .1 percent of impurities. Somebody took a nibble out of THAT enchilada!!

Bewley Steve it does not say if a cent. .999 of a cent cannot exist. It in simply comparing 2 numbers that can never be equal without rounding.

WRONG. It is an approximation.

Great question… Answer is short and concise yet could have gone on splain that numbers are simply a human construct.

Approximation was not in the clue. Your new math is wrong

Decimals cannot accurately depict 1/3 because of the approximation of the fraction. Adding .333333333333 three times will NEVER equal 1 because of that approximated decimal. Fractions themselves, on the other hand, can add together to equal a whole. So, this is an outright disaster of a question.

In the case of an infinite decimal, again standing in for the kind of infinite sequence of terminating decimals we saw above, we identify the sequence with its limit. This is what we mean when we say that 0.999... = 1

Rounded up, yes, but does it actually and totally equal 1? No, it will always be a little short

This is very badly worded. "is .99999 equal 1" is a yes or no answer not true or false. Should be worded ".9999.. = 1" true or false. Of course that totally ignores the fact that while .99999... approaches 1, it is never equals the value.

David Grover, read the explanation again. IN MATHS 0.999...= 1 and it has nothing to do with rounding a number up.

Alan Richter, different situation entirely. IN MATHS 0.999....=1. Read the explanation again. Even maths would not say that 999=1000 - it doesn't.

.99999999999999999999 will never be equal to 1. This answer is wrong

A little bit of kids' stuff here? 🙄

Alan Richter, Not the same. the three periods after the .999 mean that the 9's repeat forever.

Is it true.... takes an answer of the form [yes,no], not [true,false].

This is WRONG. Who came up with this ridiculour question and incorrect answer pair? 👎

All those saying the answer is incorrect obviously don’t just not understand mathematics but also haven’t read the explanation in the answer that gives a good proof that 0.999…. (recurring forever) DOES exactly equal 1. Although it seems as if this is not possible, and that it should be a small amount less than 1, the question in this case would have to be “tell me how much less than 1, 0.999… actually is?” Because it’s impossible to say what the difference between the two numbers is, they must be the same. The proof that these are the same is a fairly standard and easy proof that children at the age of 15 learn in Secondary school in the U.K. and I’m sure around the world too.
