Answer for screen readers
The decimal form of the fraction $\frac{1}{5}$ is $0.2$.
Steps to Solve
- Set up the division We want to divide 1 by 5. We can write this as:
$$ 1 \div 5 $$
- Identify how many times 5 goes into 1 Since 5 is greater than 1, it goes into 1, 0 times. We can write down 0 as part of our decimal:
$$ 0. $$
- Add a decimal point and a zero We place a decimal point after the 1 and add a zero to continue the division. Now we are effectively dividing 10 by 5:
$$ 10 \div 5 $$
- Divide 10 by 5 Now we divide 10 by 5, which equals 2:
$$ 5 \times 2 = 10 $$
So we write down 2 in the decimal:
$$ 0.2 $$
- Final Result Since 1 divided by 5 is complete, our decimal form of the fraction is:
$$ 0.2 $$
The decimal form of the fraction $\frac{1}{5}$ is $0.2$.
More Information
