Sagot :
bonjour
1740 = 174x10 = 2x87x2x5 = 2x2x3x5x29
2610=261x10 = 9x29x2x5 = 2x3x3x5x29
et au final
1740/2610 = (2x2x3x5x29) / (2x3x3x5x29) = 2/3
bonjour,
1740/2 =870
870/2 =435
435/3 =145
145/5= 29
=> 2*2*3*5*29
2610/2 =1305
1305/3 =435
435/3 =145
14/5 =29
=> 2*3*3*5*29
en commun:
2-3*5*29 =870
1740/870 =2
2610/870 =3
1740/ 2610= 2/3
