Réponse:
[tex] \frac{2268}{648} = \frac{7}{2 } [/tex]
[tex] \frac{90}{630} = \frac{1}{7} [/tex]
[tex] \frac{1458}{1134} = \frac{9}{7} [/tex]
[tex] \frac{5400}{1440} = \frac{15}{4} [/tex]
Explications étape par étape:
[tex] \frac{2268}{648} = \frac{2 {}^{2} \times {3}^{4} \times 7 }{ {2}^{3} \times {3}^{4} } = \frac{7}{2} [/tex]
[tex] \frac{90}{630} = \frac{2 \times {3}^{2} \times 5}{2 \times {3}^{2} \times 5 \times 7 } = \frac{1}{7} [/tex]
[tex] \frac{1458}{1134} = \frac{2 \times {3}^{6} }{2 \times {3}^{4} \times 7 } = \frac{ {3}^{2} }{7} = \frac{9}{7} [/tex]
[tex] \frac{5400}{1440} = \frac{ {2}^{3} \times {3}^{3} \times {5}^{2} }{ {2}^{5} \times {3}^{2} \times 5 } = \frac{15}{4} [/tex]
