123 Lincoln Ave.
Anytown, OH zip

456 Main St.
Yourtown, CA zip
It depends. If a space is put after the number, than it does need a period. (5 in.) If a space is not separating the numerical value and the abbreviation, then no. (5in) I have no clue why and think this is a really weird and pointless rule of the English language. :) Hope I could help
Well, there's supposed to be one after etc. but many people leave it off. It's pretty much widely accepted now, although you may want to leave the period on if you are writing a paper or a professional letter.
In math, use ~. In medicine, use app. In most other contexts, use approx. For dates, see the related questions.
Put it at the end after a comma like this: King, Martin Luther, Jr.
You put a period at the end of the sentence to indicate that the sentence has ended.
We put the period after the word Mr because it's an abbreviation for Mister.
No. You put only one period.
no spaces
Yes you should always use a period.
In an address, you do not put a period after the word "street." For example: 11 Mulberry Street Fort Worth, Texas 12345 However, if you abbreviate the word "street" to "st." you DO put the period. For example: 11 Mulberry St. Fort Worth, Texas 12345
No, you do not need to add an additional period at the end of a sentence that already ends with an abbreviation like Oct. The period from the abbreviation serves as the ending punctuation for the sentence.
No you do not. Info. is an abbreviation and therefore requires a full stop
No, but you need to capitalize it. You put a period after Mr. because it is short for Mister. You put a period after Mrs. because it is short for Missus. But Miss is already a short word so doesn't need an abbreviation.
No. It is not necessary to put a period/fullstop after the m, because the letter is not used as an abbreviation. Instead, the letter m is a symbol used to represent the unit "metres."
No, it is not necessary to put a dot after "St" when abbreviating the word "Street". It is commonly accepted to use "St" without a period in informal writing.
Yes. Etc. is an abbreviation. yes yes yes yes yes
It depends. If a space is put after the number, than it does need a period. (5 in.) If a space is not separating the numerical value and the abbreviation, then no. (5in) I have no clue why and think this is a really weird and pointless rule of the English language. :) Hope I could help
