Explications étape par étape:
[tex]g = - \frac{6}{7} + 3 = - \frac{6}{7} + \frac{3}{1} = \frac{6 \times 1}{7 \times 1} + \frac{3 \times 7}{1 \times 7} = - \frac{6}{7} + \frac{21}{7} = \frac{ - 6 + 21}{7} = \frac{15}{7} [/tex]
[tex]h = 5 - \frac{14}{24} = \frac{5}{1} - \frac{14}{24} = \frac{5 \times 24}{1 \times 24} - \frac{14 \times 1}{24 \times 1} = \frac{120}{24} - \frac{14}{24} = \frac{120 - 14}{24} = \frac{106}{24} = \frac{2 \times 53}{2 \times 3 \times 4} = \frac{53}{12} [/tex]
