Quelqu’un peux m’aider svp merci

Réponse :

A = x - y = 3/5 - 1 = -2/5

B = x*z = 3/5 * 0.3 = 9/50 (=0.18)

C = x/z = (3/5) / 0.3 = 2/1 (=2)

Explications étape par étape

Bonjour

x = 3/5

y = 1

z = 0,3

t = 1/2

A = x - y

A = 3/5 - 1

A = 3/5 - 5/5

A = -2/5

B = xz

B = 3/5 * 0,3

B = 3/5 * 3/10

B = 9/50

C = x/z

C = 3/5 / 0,3

C = (3/5) / (3/10)

C = 3/5 x 10/3

C = 3/3 x 10/5

C = 1 x 2

C = 2
