Here are the answer options

Hero:

And which answer do you think is the correct one

Hero:

If anyone gives the answer actions will be taken against your account

Noodlearms:

I think it would be #3

jordangantt12:

You are correct noodles

Noodlearms:

Oh, great! Okay, thank you!

Hero:

You have to be certain before you say whether or not an answer is correct

jordangantt12:

I am...

Hero:

The bar above the digits say that those digits repeat

Hero:

There's only one such case where the barred digits repeat

jordangantt12:

Exactly and .05 would repeat

jordangantt12:

I only care if it was right or not because if it was I rest my case

Hero:

Expanding the repeating digits of each case would probably help

jordangantt12:

You make it sound like isk what i'm doing

4804268234:

yeah i think

jordangantt12:

idk*

4804268234:

i don't know zzzzzzzzz

Hero:

I'm just giving hopeful clues. No one is trying to make anyone feel bad here

jordangantt12:

ok...

Noodlearms:

Thank you so much for all your help

Hero:

@noodlearms have you yet stated which answer you think is correct?

4804268234:

your welcome

jordangantt12:

No problem lovely (btw I call everyone love so no i'm not hitting on anyone)

4804268234:

any more help

Noodlearms:

Yes, 5.05 with the line above 05

jordangantt12:

Ok good

Hero:

@noodlearms are you 100 percent sure?

Noodlearms:

84% sure.

Hero:

Notice that in the original decimal number, for the first four digits there are two zeros between the fives

Hero:

The correct answer choice would reflect that same consistency.

Noodlearms:

So, which ever one has two zeros with the line above them?

Hero:

Well there's more than one as a choice that has that consistency however we can at least eliminate the incorrect choice by using same that logic

Hero:

Process of elimination is the default method by which to approach problems that have answer choices

Noodlearms:

So, you don't think it's 5.05?

Hero:

It's the choice that I would have eliminated

Hero:

Knowing that we now have three choices from which to ponder as to which is correct

Noodlearms:

Oh alrighty, my second guess would be 5.005

Hero:

Well keep in mind that the bar signifies repeating digits

Hero:

So whatever digits exist under the bar those are digits repeat so take whichever answer you think is correct and then repeat the digits and see if it matches the original decimal number

Noodlearms:

Oh, that is so helpful! Thank you so much

Hero:

It isn't over until you have stated what the correct answer choice is.
