Answer for screen readers
The decimal equivalent of the fraction $\frac{3}{10}$ is $0.3$.
Steps to Solve
- Set Up the Division
We need to divide the numerator (3) by the denominator (10). This can be expressed as:
$$ 3 \div 10 $$
- Perform the Division
When we divide 3 by 10, we can think about how many times 10 goes into 3. Since 10 is larger than 3, we write it as a decimal:
$$ 3 \div 10 = 0.3 $$
- Confirming the Result
You can check your answer by multiplying the decimal result by the denominator:
$$ 0.3 \times 10 = 3 $$
Since this is equal to the numerator, our division was performed correctly.
The decimal equivalent of the fraction $\frac{3}{10}$ is $0.3$.
