Step 1. Count the number of repeating digits.
Step 2. Multiply the number by 10 to that power.
Step 3. From that product, subtract the original number.
Step 4. Divide the result by 1 less than the multiplier of Step 2.
Step 5, Reduce the fraction.

For your number
3. \overline{152}
Step 1. There are 3 repeating digits
Step 2. The multiplier is
10^(3)=1000. The multiplied number is

1000 \cdot 3. \overline{152}=3152. \overline{152}
Step 3. Subtract the original number

3152. \overline{152}-3. \overline{152}=3149
Step 4. Divide by 1000 - 1 = 999

(3149)/(999)=3 (152)/(999)
This fraction does not reduce, so you are done.
