1 . Oblicz pamiętając o kolejności wykonywania działań:

(15 2/3 - 7 1/2): 1 1/2 =

2 *(1/3)Do potęgi 2 + 3 *(1/2) Do potęgi 3 =

4 1/2 * 1 1/3 - 2 2/5 * 5/7 =

1 2/3 - 5/6 + 2 1/10 :1 6/15 =

(5/8 + 1/2) : 1 1/2 - 1/3 =

Proszę o rozpisanie tego wszystkiego !!!

Pilne !!!!

Answer 1

= (15 4/6- 7 3/6): 1 1/2= 8 1/6 : 1 1/2 = 49/6 * 2/3= 49/9 = 7

= 2 * 1/9 + 3* 1/8 = 2/9 + 3/8 = 16/72 + 27/72 = 43/72

= 9/2 * 4/3 - 12/5 * 5/7 = 6 - 1 5/7 = 4 2/7

= 1 4/6 - 5/6 + 21/10 * 15/21 = 5/6 + 3/2 = 5/6 + 9/6 = 14/6= 2 2/6= 2 1/3

= (5/8 + 4/8)* 2/3 - 1/3= 9/8 * 2/3 - 1/3 = 3/4 - 1/3 = 9/12 - 4/12 = 5/12

Answer 2

(15 4/6- 7 1/2): 1 1/2= 8 1/6 : 1 3/6 = 49/6 * 6/9= 49/9=5 4/9

2 * 1/9 + 3* 1/8 = 2/9 + 3/8 = 16/72 + 27/72 = 43/72

9/2 * 4/3 - 12/5 * 5/7 = 6 - 12/7 = 4 2/7

1 4/6 - 5/6 + 21/10 * 15/21 = 5/6 + 3/2 = 5/6 + 9/6 = 14/6= 2 2/6= 2 1/3

(5/8 + 4/8)* 2/3 - 1/3= 9/8 * 2/3 - 1/3 = 3/4 - 1/3 = 9/12 - 4/12 = 5/12
