Bonjour.
13/18 = irréductible car 13 et 18 n'ont aucun diviseur commun.
20/30 = ( 2 × 10 ) / ( 3 × 10 ) = 2/3
25/10 = ( 5 × 5 ) / ( 2 × 5 ) = 5/2
15/12 = ( 5 × 3 ) / ( 4 × 3 ) = 5/4
25/10 = ( 5 × 5 ) / ( 2 × 5 ) = 5/2
15/12 = ( 5 × 3 ) / ( 4 × 3 ) = 5/4
Bonjour
13/18⇒déjà irreductible
20/30⇒(2×10)/(3×10)=2/3
25/10⇒(5×5)/(5×2)=5/2
15/12⇒(5×3)/(4×3)=5/4
13/18⇒déjà irreductible
20/30⇒(2×10)/(3×10)=2/3
25/10⇒(5×5)/(5×2)=5/2
15/12⇒(5×3)/(4×3)=5/4
