- 0.1

We want to write the given fraction as a decimal number. - 1/9Let's ignore the negative sign for just a moment. Recall that 1 9 means 1Ă· 9. Therefore, we will divide the numerator by the denominator. Let's do it!
We can see that the pattern starts to repeat itself after a few steps. This means that the decimal is a repeating decimal. We can write it using bar notation. Remember, the bar goes over the decimal part that repeats itself. 0.111111... = 0.1 Therefore, - 19 written as a decimal is - 0.1.
