write a fraction equivalent to $\frac{1}{2}$ with a denominator of 10.
$\frac{1×\boxed{4}}{2×\boxed{4}} = \frac{\boxed{4}}{10}$

Explanation:

Step1: Find denominator multiplier

To get denominator 10 from 2, calculate $10 \div 2 = 5$.

Step2: Multiply numerator and denominator

Multiply numerator and denominator of $\frac{1}{2}$ by 5:
$\frac{1 \times 5}{2 \times 5} = \frac{5}{10}$

Answer:

The missing number is 5, so $\frac{1}{2} = \frac{5}{10}$
The correct filled equation is $\frac{1 \times 5}{2 \times 5} = \frac{5}{10}$
