Solve: Find the Unknown Factor in (3/5 × ? = 2/4)

To solve this problem, we need to find the missing fraction $x$ such that $\frac{3}{5} \times x = \frac{2}{4}$. We'll follow these steps:

• Step 1: Simplify the fraction $\frac{2}{4}$ to $\frac{1}{2}$.
• Step 2: Set up the equation to solve for $x$. This gives us $\frac{3}{5} \times x = \frac{1}{2}$.
• Step 3: Isolate $x$ by dividing both sides by $\frac{3}{5}$, leading to $x = \frac{\frac{1}{2}}{\frac{3}{5}}$.
• Step 4: Simplify the complex fraction by multiplying by the reciprocal: $x = \frac{1}{2} \times \frac{5}{3}$.
• Step 5: Calculate the multiplication: $x = \frac{1 \times 5}{2 \times 3} = \frac{5}{6}$.

Therefore, the solution to the problem is $\frac{5}{6}$.
