A= 3/2 - 1/3 / 3/4 + 2/3 B=7/5+8/15/2/3-19/2 Pouvez vous résoudre cela ? Merci

Bonjour,

A= 3/2 - 1/3 / 3/4 + 2/3

(1/3)/(3/4) = 1/3 * 4/3

=3/2 - 1/3 * 4/3  +2/3

= 3/2 - 4/9 +2/3

= 27/18 - 8/18+12/18

= 31/18

B=7/5+8/15/2/3-19/2

 8/15/2/3 = 8/15 * 3/2 = 24/30 = 12/15 = 4/5

= 7/5 +4/5 -19/2

= 11/5 -19/2

= 22/10 - 95/10

= -73/10
