Answer 1

5,(6) = (56-5)/9 = 51/9 (impartim prin 3) = 17/3

3,75 = 375/100 (impartim prin 25) = 15/4

1 intreg si 1/8 = (8 * 1 + 1)/8 = 9/8


Rezolvare:

{7/36 - 1/46 * [ 5,(6) - 3,75]} : 1 integ si 1/8

{7/36 - 1/46 * [ 17/3 - 15/4 ]} : 9/8


17/3 (amplificam cu 4) = 68/12

15/4 (amplificam cu 3) = 45/12



{7/36 - 1/46 * [ 68/12 - 45/12 ]} : 9/8


{7/36 - 1/46 * 23/12} : 9/8

{7/36 - 23/552} : 9/8


23/552 (simplificam prin 23) = 1/24



{7/36 - 1/24} : 9/8


7/36 (amplificam cu 4) = 28/144
1/24 (amplificam cu 6) = 6/144


{28/144 - 6/144} : 9/8

22/144 : 9/8

22/144 * 8/9

176/1296 = 11/64
