Svp merci beaucoup 6/5=24/. 15/32=30/. ./7=54/63. 11/.=33/42 8/11=./66

Bonjour,

6/5 = (6 x 4) / (5 x 4) = 24/20

15/32 = (15 x 2) / (32 x 2) = 30/64

(9 x 6) / (9 x 7) = 6/7 = 54/63 

(3 x 11) / (3 x 14) = 11/14 = 33/42

8/11 = (8 x 6) / (11 x 6) = 48/66

Bonjour. :)
[tex] \frac{6}{5} = \frac{6 * 4}{5 * 4} = \frac{24}{30} [/tex]

[tex] \frac{15}{32} = \frac{15 * 2}{32 * 2} = \frac{30}{64} [/tex]

[tex] \frac{54}{63} = \frac{54 : 9}{63 : 9} = \frac{6}{7} [/tex]

 [tex] \frac{33}{42} = \frac{33 * 3}{42 : 3} = \frac{11}{14} [/tex]

[tex] \frac{8}{11} = \frac{8 * 6}{11 * 6} = \frac{48}{66} [/tex]


Bonne journée ! ;)
