Question

what is the answer to this - 2/4 = ?/2

Answer 1

2/4 = 1/2 since it can be simplified but there are other options like 6/12 5/10 20/40, because they all represents 1 half

Answer 2

$\frac{2}{4} = \frac{x}{2} \\ \\ \frac{1}{2} = \frac{x}{2} \\ \\ \frac{1}{2} \times 2 = x \\ \\ 1 = x \\ \\ x = 1$

The final result is: x = 1.
