Olá bom dia!
[tex]\frac{5}{4} - \frac{1}{2} = \frac{1*5-1*2}{4} = \frac{5-2}{4} = \frac{3}{4}[/tex]
[tex]\frac{1}{3} + \frac{2}{5} = \frac{1*5+3*2}{15} = \frac{5+6}{15} = \frac{11}{15}[/tex]
[tex] = \frac{5}{4} - \frac{1}{2} \\ \\ = \frac{5 - 2}{4} \\ \\ = \frac{3}{4} \\ \\ > \geqslant > > > > > > > > > > > > > \\ \\ = \frac{1}{3} + \frac{2}{5} \\ \\ = \frac{5 + 6}{15} \\ \\ = \frac{11}{15} [/tex]
