Bonsoir,

$A = (-4 + 3 \times \frac{2}{7}) : \frac{3}{14}$

$A = (-4 + \frac{6}{7}) \times \frac{14}{3}$
$A = (\frac{-28}{7} + \frac{6}{7}) \times \frac{14}{3}$
$A = \frac{-22}{7} \times \frac{14}{3}$
$A = \frac{-44}{3}$

$B = \frac{4 - (2 - 5)^{2}}{4 + 5}$
$B = \frac{4 - (-3)^{2}}{9}$
$B = \frac{4 - 9}{9}$
$B = \frac{-5}{9}$

$C = (\frac{3}{2})^{2} - \frac{1}{3} \times \frac{-5}{2}$
$C = \frac{9}{4} + \frac{5}{6}$
$C = \frac{27}{12} + \frac{10}{12}$
$C = \frac{37}{12}$

Je te laisse faire la D

Bonsoir

A=(-4+3*2/7):3/14=
(-4+6/7):3/14=
( -28/7+6/7):3/14=
-22/7:3/14=
-22/7*14/3=-308/21=-44/3

b = 4-(2-5)² =4-(-3)²=4-9=-5
4+5=9
= -5/9

c=(3/2)²-1/3*(-5/2)=
(3/2)²+5/6=
9/4+5/6=
54/24+20/24=74/24=37/12

d=5+(1+1/8):3/4=
5+(8/8+1/8):3/4=
5+ 9/8:3/4=
5+9/8*4/3=
5+36/24=
120/24+36/24=
156/24=13/2
