Bonjour

E = 40/48 + 105/27 x 90/56

E = 40/48 + 9 450/1 512

E = 40/48 + (378 x 25) / (378 x 4)

E = 40/48 + 25/4

E = (2 x 20) / (2 x 24) + (25 x 6) / (4 x 6)

E = 20/24 + 150/24

E = 170/24

E = (2 x 85) / (2 x 12)

E = 85/12

F = (- 12/14 + 20/35) x 98/25

F = [(2 x - 6) / (2 x 7) + (5 x 4) / (5 x 7)] x 98/25

F = (- 6/7 + 4/7) x 98/25

F = - 2/7 x 98/25

F = - 196/175

F = (7 x - 28) / (7 x 25)

F = - 28/25.

E = 40/48 + 105/27 x 90/56

E = (8 x 5)/(8 x 6) + (3 x 35)/(3 x 9) x (2 x 45)/(2 x 28)

E = 5/6 + 35/9 x 45/28

E = 5/6 + 45/9 x 35/28

E = 5/6 + (5 x 9)/9 x (7 x 5)/(7 x 4)

E = 5/6 + 5 x 5/4

E = 5/6 + 25/4

E = (5 x 2)/(6 x 2) + (25 x 3)/(4 x 3)

E = 10/12 + 75/12

E = 85/12

F = (-12/14 + 20/35) x 98/25

F = [(-2 x 6)/(2 x 7) + (5 x 4)/(5 x 7)] x 98/25

F = (-6/7 + 4/7) x 98/25

F = -2/7 x 98/25

F = -98/7 x 2/25

F = -14 x 2/25

F = -28/25
