aren't .7 and .70 the same?

apparently my teacher begs to differ on that. she says .70 is set in the hundreths place. thats dumb. the calculator corrects .70 as the tenths place.

That is why your Teacher is still teaching. Tell her I said that!
@swirlie: This unscientific and baseless reply being voted best answer tells you a lot about both of you.

@Existentior:

You are obviously the type of macho guy who is a cry baby deep down inside. I feel very sorry for you, you poor little man.

'Bohemianbrassstrings', I would officially like to put on record that I am voluntarily forfeiting my "Best Answer" ribbon to 'Existentior' so that he can go home to his mother with the prize he most probably said he would win for the family. His mother will then be very proud of him. Far be it from me to stand between 'Existentior' and a green ribbon.

Please remove my name from the roster and put Existentior's name in my place so that the intelligence and maturity of his own answer can shine through, making it obvious to everyone here as well as at his home, precisely 'why' he should win this 'Best Answer' contest, 'hands down'. Thank you.

Yours sincerely,
Ms. swirlie
He'll get over it. @swirlie:

It really just depends on how many decimal places you were instructed to give the answer in. If she said answer to the nearest hundredth, then she wants .70.

Tell your teacher that their is going to a sale next week in the shops and every thing will be half of twice the amount guaranteed
@antonioio: lol good one

It depends. It does make a difference when computing margins of error. If a measurment is only accurate to tenths you cannot assume hundreths.

I was taught that they are the same, and the Zero is implied.
@3venus: i was taught the same way. i should have gotten higher than an 76% on my exam.
3venus · F
@Bohemianbrassstrings: Are you allowed to contest the score?
@3venus: i already had. i used up all my retake points. i can't now. i'm going to my advisor.

What class? In scientific contexts, they imply different levels of precision.
@OggggO: well with measurments of course.... but this is math... developmental math.

@Bohemianbrassstrings: Then I don't know what her problem is.

I'm not a mathematician but to me they're exactly the same and more importantly, mean exactly the same. 70% is 70% however you write it.
Quizzical · 46-50, M
The zero means nothing. They are the same value.
dumpstermeow · 41-45, F
They're both wrong. 0.7 is the correct way to state it
amoonlitbarn · 31-35, M
Well, to be really technical. 70 is more accurate than. 7 (relatively speaking)

Cuz you could have derived. 7 from any of. 71,. 72,. 73 or. 74

But mathematically and not relatively, they both are the same.

.70 is more accurate then .7 and they are equal at the tollerance of the lesser decimal
thats what i thought. i'm talking to my advisor about her grading
Quizzical · 46-50, M
@Bohemianbrassstrings: If you are required to give an answer to a certain number of decimal places then you would have to include the zeros.
Noble · 56-60, M
Correct. But if the hundredths is required, it needs to be written as 0.70
this is basic math people not computer programming. just a general math class.
0.7, .7, .70, .7000 are all the same.

@CopperCicada: tell that to the calculator...

@Bohemianbrassstrings: could it be that you have your calculator on the wrong setting? Most calculators give the user an option of, to how many decimal places an answer should be displayed. If you've chosen one decimal place, then you've restricted your level of precision.
