How do you Write a fraction as a repeating decimal?

Answer 1

What you would do is divide the top number, the numerator, by the bottom number, the denominator, to get the decimal. Then you would find a number like 3.333 but the 3 would keep going on. You would just wright 3.3 with a like right above the 3 in the tenths place. And that's how you would wright a repeating decimal.

Answer 2

it is just easier that way. for example 0.3333333 is harder to read and understand than 1/3

Answer 3

You can treat a repeating decimal like a geometric series for example:

.282828282.......-> 28/10^2+28/10^4+28/10^6+28/10^6+.....

=(28/10)(1/(1-1/10))=28/90
