To convert \( \frac{1}{5} \) to a decimal, you can think of it as dividing 1 by 5.
When you divide 1 by 5, you can set it up as follows:
- 5 goes into 1 zero times (0).
- We can add a decimal point and a zero to 1, making it 10.
- Now, 5 goes into 10 two times (2), since \( 5 \times 2 = 10 \).
- After subtracting 10 from 10, we have 0 left.
So, \( \frac{1}{5} = 0.2 \).
Thus, the decimal representation of \( \frac{1}{5} \) is \( 0.2 \).
