Answer 1

Explicație pas cu pas:

1 + 5 / 6 - 1  2 / 3 =

= 1 + 5 / 6 - ( 1 x 3 + 2 ) / 3

= 1 + 5 / 6 - ( 3 + 2 ) / 3

= 1 + 5 / 6 - 5 / 3

= 6 / 6 + 5 / 6 - 10 / 6

= 11 / 6 - 10 / 6

= 1 / 6

6  1 / 4 + 3 / 8 + 1 / 12 =

= ( 6 x 4 + 1 ) / 4 + 3 / 8 + 1 / 12

= ( 24 + 1 ) / 4 + 3 / 8 + 1 / 12

= 25 / 4 + 3 / 8 + 1 / 12

= 150 / 24 + 9 / 24 + 2 / 24

= 159 / 24 + 2 / 24

= 161 / 24
