\[ \begin{array}{rlr} \frac{7}{8} \times \frac{12}{7} & = \frac{7 \times 12}{8 \times 7} & \text{Multiply numerators and denominators.} \\ & = \frac{7}{7} \times \frac{12}{8} & \text{Rearrange factors to show a common factor.} \\ & = 1 \times \frac{12}{8} & \frac{7}{7}=1 \\ & = \frac{12}{8} & \\ & = \frac{3}{2} & \text{Simplify by dividing numerator and denominator by 4.} \end{array} \]

Let’s consider the multiplication \( \frac{3}{4} \times \frac{4}{5} \). \[ \begin{array}{rlr} \frac{3}{4} \times \frac{4}{5} & =\frac{3 \times 4}{4 \times 5} & \begin{array}{l} \text { Multiply numerators. } \\ \text { Multiply denominators. } \end{array} \\ & =\frac{4 \times 3}{4 \times 5} & \\ & =\frac{4}{4} \times 3 & \frac{4}{4}=1 \\ & =\frac{3}{5} & \\ & & \text { Final Result. } \end{array} \] This example follows the same structure by multiplying the numerators and denominators, and it conveniently showcases the property of the identity element (where \( \frac{4}{4} = 1 \)). Moreover, this method emphasizes how recognizing equivalent fractions simplifies the process! When you're faced with fractions, remember that canceling common factors can save you time and effort!
