Rozwiąż zadania :

a) Oblicz :

- (| 5 - 16 |) x (-17)) : 21 + 2:3

- 2,(27) - o,4 x 2/3

- (( - 29 x | 4 - 12 |) + 173 ) : 18 + 5 : 6

- 5/11 x o,4 + 3,(36)

Proszę o podanie obliczeń :) Z góry dziękuję za pomoc :)

Answer 1

(| 5 - 16 |) x (-17)) : 21 + 2 : 3 =

(|- 11 |) x (-17)) : 21 + 2 : 3 =

11 x (-17)) : 21 + 2 : 3 =

-11/17 * 1/21 + 2/3 =

-11/357 + 2/3 = -11/357 + 238/357 = 227/357

 

2,(27) - o,4 x 2/3 =

2 i 27/99 - 4/10 x 2/3 =

2 i 3/11 - 4/15 =

2 i 45/165 - 44/165 = 2 i 1/165

 

(( - 29 x | 4 - 12 |) + 173 ) : 18 + 5 : 6 =

(( - 29 x | - 8 |) + 173 ) : 18 + 5 : 6 =

(( - 29 x 8 ) + 173 ) : 18 + 5 : 6 =

(( - 232) + 173 ) : 18 + 5 : 6 =

(-59 ) : 18 + 5 : 6 =(-59 ) : 18 + 5 : 6 =

- 59/18 + 5/6 = -59/18 + 15/18 = - 44/18 =  - 22/9 = - 2 i 4/9

 

 

5/11 x o,4 + 3,(36) = 5/11 x 4/10 + 3 i 36/99 = 4/22 + 3 i 9/11 = 2/11 + 3 i 9/11 = 3 i 11/11 = 4
