-2/15

Explanation:

We first let -0.13 (3 being repeated) be x.

Since x is recurring in 1 decimal places, we multiply it by 10^1.

10x = -1.33

Next, we subtract them.

10x - x = -1.33 - (-0.13)

9x = -1.2

Lastly, we divide both sides by 9 to get x as a fraction.

x = -1.2/9

= -12/90

= -2/15

-0.13
x=-0.133
10x=-1.33
100x=-13.33
100x-10x=-13.33-1.33
90x=-14.66
x=-1466/9000
now cancel it by yourself
