bonjour
A = - 14/15 - 9/10
= - 28/30 - 27/30
= - 55/30
= - 11 /6
B = ( 15/24 - 28/24) * ( 56/35 + 3/35)
= - 13/24 * 59/35
= - 767/840
C = 8/3 + 10/21
= 56/21 + 10 /21
= 66/21
= 22/ 7
le 2 est difficilement lisible
1/4 * 5/6 = 5/24
Thomas a mangé les 5/24
1/2 * 3/4 = 3/8
Tom les 3/8
3/8 = 9/24
donc Tom en a mangé le plus
( 5/3)² = 1 ²+( 4/3)²
25/9 = 1 + 16/9
25/9 = 9/9 + 16/9
25/9 = 25 / 9
P = 1 + 5/3 + 4/3
P = 3/3 + 5/3 + 4/3 = 12/3 = 4
A = ( 1 * 4/3) /2 = 4/3 x 1/2 = 4/6 = 2/3
