The expected outcome would be \( \frac{2}{4} \), which simplifies to \( \frac{1}{2} \).
When dealing with multiplication and division, these operations can also be conducted on fractions. For multiplication, entering \( \frac{1}{2} \times \frac{2}{3} \) involves similar steps: input \( 1 \), use the division key for \( 2 \), select the multiplication operator, enter \( 2 \), and then \( 3 \) with the division key. The result should yield \( \frac{2}{6} \) or simplified, \( \frac{1}{3} \). In division, the process follows suit, where \( \frac{1}{2} ÷ \frac{1}{4} \) would require entering \( 1 \) divided by \( 2 \), then the division operator, followed by \( 1 \) divided by \( 4 \). The output will be \( 2 \).
