Question

como resolver essa conta 2a/3+1/6 . [-a/2+1/9] -1

Answer 1

= 2a/3 + 1/6 . [-a/2+1/9] -1
= 2a/3 - a/12 + 1/54 - 1
= [36.2a - 9a + 2.1 - 1.108]/108
= [72a - 9a + 2 - 108]/108
= [63a - 106]/108

3,12,54: 2
3,6,27: 2
3,3,27: 3
1,1,9: 3
1,1,3: 3
--------------
1,1,1 = 4.27 = 108

= [ 63a - 106 ] / 108
