What are three fractions using 10 as a denominator and 1 as its sum?
I have no idea what the "sum" of a fraction means.
How do you write equivalent fractions with the lowest common denominator?
Well, isn't that just a happy little question! To write equivalent fractions with the lowest common denominator, you first find the least common multiple of the denominators. Then, you rewrite each fraction using that common denominator. It's like painting a beautiful landscape - just take your time, follow the steps, and soon you'll have a lovely set of equivalent fractions.
Why do you need a common denominator when you add fractions?
Unless you are using a calculator that adds them for you, it is much harder to add fractions with uncommon denominators. Having the same denominator allows you to only have to add the numerators for your answer.

How do you write 3 8ths as a fraction on a pc?
The standard method to write any fraction is to write the numerator followed by a slash (/) followed by the denominator → three eights is 3/8 To improve the look, the numerator can be made superscript and the denominator made subscript. However, Unicode includes three eighths as a character ⅜ which I type using [Alt Gr][<SHIFT>][5] on this Linux box.
