simplifier les franctions suivantes:
90/54=(9x10)/(6x9)
=10/6=5/3
32/72=(8x4)/(9x8)
=4/9
90/54=(9x10)/(6x9)
=10/6=5/3
32/72=(8x4)/(9x8)
=4/9
[tex] \frac{90}{54} = \frac{2*5*3*3}{2*3*3*3} = \frac{5}{3}
\frac{32}{72} = \frac{2*2*2*2*2}{2*2*2*3*3} = \frac{4}{9} [/tex]
\frac{32}{72} = \frac{2*2*2*2*2}{2*2*2*3*3} = \frac{4}{9} [/tex]
