2/4 :3

To simplify the ratio \( \frac{2}{4} : 3 \), you can first simplify \( \frac{2}{4} \) to \( \frac{1}{2} \). So, the expression becomes: \[ \frac{1}{2} : 3 \] This can also be expressed as a fraction: \[ \frac{1}{2} \div 3 = \frac{1}{2} \times \frac{1}{3} = \frac{1}{6} \] Thus, the ratio \( \frac{2}{4} : 3 \) simplifies to \( \frac{1}{2} : 3 \) or \( 1 : 6 \) when expressed in simplest integer form. So, in integer form, the simplified ratio is \( 1 : 6 \).
