A = 12/5 + 3/5 x - 7/9A = 12/5 - 21/45
A = 12 x 9 / 5 x 9 - 21/45
A = 108/45 - 21/45
A = 87/45
A = 3 x 29 / 3 x 15
A = 29/15
B = - 2 - 4/3
1 + 7/6
B = - 2 x 3 / 1 x 3 - 4/3
1 x 6 / 1 x 6 - 7/6
B = - 6/3 - 4/3
6/6 - 7/6
B = - 10/3 : - 1/6
B = - 10/3 x - 6/1
B = 60/3
B = 3 x 20 / 3 x 1
B = 20/1
B = 20
