Svp je n arrive pas a faire cet fraction on peu m aider svp (8/3+1/9)-(2/3+4/3)= merci

Bonsoir,

(8/3 + 1/9) - (2/3 + 4/3)
= (8 x 3 / 3 x 3 + 1/9) - (2 x 3 / 3 x 3 + 4 x 3 / 3 x 3)
= (24/9 + 1/9) - (6/9 + 12/9)
= 25/9 - 18/9
= 7/9

(8/3+1/9)-(2/3+4/3)
=(8*3/3*3+1/9)-6/3
=(24/9+1/9)-6/3
=25/9-6/3
=25/9-6*3/3*3
=25/9-18/9
=7/9
