Step 1:
Write the two expression
[tex]\frac{4}{6}\text{ and }\frac{10}{15}[/tex]Step 2:
To simplify each expression, divide the numerator and denominator by the same factor.
[tex]\begin{gathered} \text{Simplify }\frac{4}{6}\text{ by dividing both numerator and denominator by 2} \\ \frac{4}{6}\text{ = }\frac{2}{3} \\ \text{Simplify }\frac{10}{15}\text{ by dividing both numerator and denominator by }5 \\ \frac{10}{15}\text{ = }\frac{2}{3} \end{gathered}[/tex]Final answer
[tex]\begin{gathered} \frac{4}{6}\text{ = }\frac{2}{3} \\ \frac{10}{15}\text{ = }\frac{2}{3} \end{gathered}[/tex]
