Answer 1

1.

 

a) = 0

 

m = -1/2 + 1/3

m = -3/6 + 2/6

m = -1/6

 

b) = 0

 

m = -2/5 + 3/4

m = -8/20 + 15/20

m = -7/20

 

c) = 0

 

2m = 4/3 - 9/4

2m = 16/12 - 27/12

2m = -11/12

m = -11/12 * 1/2

m = -11/24

 

d) = 0

 

7/3m = -7/2 + 7/6

7/3m = -21/6 + 7/6

7/3m = -14/6

m = -14/6 * 3/7

m = -42/42

m = -1

 

e) = 0

 

2/3m = 3/2 - 3/4

2/3m = 6/4 - 3/4

2/3m = 3/4

m = 3/4 * 3/2

m = 9/8

 

f) = 0

 

1/8m = 35 + 5/4

1/8m = 140/4 + 5/4

m = 145/4 * 8

m = 1160/4

m = 290

 

 

2.

 

a)

 

p = 22/5 : (14/30 - 3/30)

p = 22/5 : 11/30

p = 22/5 * 30/11

p = 660/55

p = 12

 

liczba >>> 11

 

b)

 

p = 11/8 : (15/12 - 14/12)

p = 11/8 : 1/12

p = 11/8 * 12

p = 132/8

p = 16,5

 

liczba >>> 16

 

c)

 

p = 3/2 - 5/3 + 1/4 * 6 - 5/12

p = 3/2 - 5/3 + 6/4 - 5/12

p = 18/12 - 20/12 + 18/12 - 5/12

p = 11/12

 

liczba >>> 0

 

d)

 

p = 1/14 + 17/8 - 3/2 : (-1/12 - 7/6)

p = 1/14 + 17/8 - 3/2 : (-1/12 - 14/12)

p = 1/14 + 17/8 - 3/2 : -15/12

p = 1/14 + 17/8 - 3/2 * -12/15

p = 1/14 + 17/8 + 36/30

p = 240/3360 + 7140/3360 + 4032/3360

p = 11412/3360

p = 3 + 1332/3360

p = 3 + 111/140

 

liczba >>> 0

 

e)

 

p = 4/5 + 21/10 - 1/2 : (3/5 - 2/15 + 1/5)

p = 4/5 + 21/10 - 1/2 : (9/15 - 2/15 + 3/15)

p = 8/10 + 21/10 - 1/2 : 10/15

p = 29/10 - 1/2 * 15/10

p = 29/10 - 15/20

p = 58/20 - 15/20

p = 43/20

p = 2,15

 

liczba >>> 2

 

f)

 

p = 10/3 - 2/9 + 1/2 : (3/18 - 5/18 + 18/18)

p = 30/9 - 2/9 + 1/2 : 16/18

p = 28/9 + 1/2 * 18/16

p = 28/9 + 18/32

p = 896/288 + 162/288

p = 1058/288

p = 3 + 194/288

p = 3 + 97/144

 

liczba >>> 3
