Explications étape par étape

Bonsoir

A = 55/12 x 18/33

A = 55/33 x 18/12

A = (5 x 11)/(3 x 11) x (3 x 6)/(2 x 6)

A = 5/3 x 3/2

A = 3/3 x 5/2

A = 5/2

B = 5/4 - 2/3 : 16/9

B = 5/4 - 2/3 x 9/16

B = 5/4 - 9/3 x 2/16

B = 5/4 - (3 x 3)/3 x 2/(2 x 8)

B = 5/4 - 3 x 1/8

B = (5 x 2)/(4 x 2) - 3/8

B = 10/8 - 3/8

B = 7/8

C = (2 + 3/4) / (17/4)

C = 2 + 3/4 x 4/17

C = 2 + 4/4 x 3/17

C = 2 + 3/17

C = (2 x 17)/17 + 3/17

C = 34/17 + 3/17

C = 37/17

D = [35 x 10^2 x 2 x (10^(-2))^6] / [42 x 10^(-10)]

D = (35 x 2 / 42) x 10^(2-2*6+10)

D = (7 x 5 x 2)/(2 x 7 x 3) x 10^(2-12+10)

D = 5/3 x 10^0

D = 5/3
