Bonjour

A= -2/5:3/15+2/15

A = - 2/5 x 15/3 + 2/15

A = - 30/15 + 2/15

A = - 28/15

B= 9/2-5/2:15/8​

B = 9/2 - 5/2 x 8/15

B = (9 x 15) / (2 x 15) - 40/30

B = 135/30 - 40/30

B = 95/30

B = (5 x 19) / (5 x 6)

B = 19/6.

Bonjour

A= -2/5:3/15+2/15

A = -2/5 x 15/3 + 2/15

A = -15/5 x 2/3 + 2/15

A = -(5 x 3)/5 x 2/3 + 2/15

A = -3 x 2/3 + 2/15

A = -3/3 x 2 + 2/15

A = -2 + 2/15

A = (-30/15) + 2/15

A = (-28/15)

B= 9/2-5/2:15/8​

B = 9/2 - 5/2 x 8/15

B = 9/2 - 8/2 x 5/15

B = 9/2 - (4 x 2)/2 x 5/(5 x 3)

B = 9/2 - 4 x 1/3

B = (9 x 3)/(2 x 3) - (4 x 2)/(3 x 2)

B = 27/6 - 8/6

B = 19/6
