Answer for screen readers
The result of dividing $0.4$ by $2$ is $0.2$.
Steps to Solve
- Set up the division
We want to divide $0.4$ by $2$. This can be set up as:
$$ \frac{0.4}{2} $$
- Perform the division
To divide, you can consider $0.4$ as a fraction:
$$ 0.4 = \frac{4}{10} $$
Now we perform the division:
$$ \frac{4}{10} \div 2 = \frac{4}{10} \cdot \frac{1}{2} $$
- Simplify the fraction
Now we simplify the multiplication:
$$ \frac{4 \cdot 1}{10 \cdot 2} = \frac{4}{20} $$
- Reduce the fraction
Next, we can simplify $\frac{4}{20}$ by dividing the numerator and denominator by $4$:
$$ \frac{4 \div 4}{20 \div 4} = \frac{1}{5} $$
- Convert to decimal
Finally, converting $\frac{1}{5}$ to decimal form gives:
$$ 0.2 $$
The result of dividing $0.4$ by $2$ is $0.2$.
More Information
Dividing by $2$ means you are essentially finding half of the number. In this case, $0.4$ is half of $0.8$, hence the result $0.2$.
Tips
- Confusing decimal placement: Ensure that you accurately place the decimal when performing division with decimals.
- Not reducing fractions: Always simplify your fractions to their lowest terms to find the final answer more easily.
