Réponse:
[tex]1 + \frac{3}{2} = \frac{1}{1} + \frac{3}{2} = \frac{2}{2} + \frac{3}{2} = \frac{5}{2} [/tex]
[tex] \frac{1}{4} - 2 = \frac{1}{4} - \frac{2}{1} = \frac{1}{4} - \frac{4}{4} = \frac{ - 3}{4} [/tex]
[tex]3 - \frac{16}{5 } = \frac{3}{1} - \frac{16}{5} = \frac{15}{5} - \frac{16}{5} = \frac{ - 1}{5} [/tex]
[tex] \frac{16}{3} - 4 = \frac{16}{3} - \frac{4}{1} = \frac{16}{3} - \frac{12}{3} = \frac{4}{3} [/tex]
le voila ❤
