Bonjour

Explications étape par étape

Ex3)

A = 6/5 ÷ (-11)/7

A = 6/5 * (-7)/11

A = -42/55

B = -3/4 ÷ (-5)/12

B = 3/4 * 12/5

B = (3*4*3)/(4*5)

B = 9/5

C = 10/3 ÷ 5/9

C = 10/3 * 9/5

C = (5*2*3*3)/(3*5)

C = 6

D = 9 ÷ 81/6

D = 9 * 6/81

D = (3*3*3*2)/(3*3*3*3)

D = 2/3

E = 2/-3 ÷ (-1)/6

E = 2/3 * 6

E = 12/3

E = 4
