Explicație pas cu pas:

$\dfrac{x}{y}\quad\text{cu}\quad \dfrac{x+1}{y+1},\quad x,y\in \mathbb{N}^* \\ \\ x(y+1) \quad\text{cu}\quad y(x+1) \\ \\xy+x \quad\text{cu}\quad yx+y \\ \\ x \quad\text{cu}\quad y\\ \\ \text{Daca }x&lt;y \Rightarrow \dfrac{x}{y} &lt; \dfrac{x+1}{y+1} \\ \\ \text{Facem }x = 11,\quad y = 25 \\ \\ \Rightarrow \dfrac{11}{25} &lt; \dfrac{12}{26} \Rightarrow \boxed{\dfrac{12}{26} &gt; \dfrac{11}{25}}$
