Answer 1

Odpowiedź:

a)

a + 2 3/5 = 7

a = 7 - 2 3/5 = 4 2/5

spr.

L = 4 2/5 + 2 3/5 = 7

P = 7

L = P

b)

3 1/2 + b = 5 1/5

b = 5 1/5 - 3 1/2 = 5 2/10 - 3 5/10 = 4 12/10 - 3 5/10 = 1 7/10

spr.

L = 3 1/2 + 1 7/10 = 3 5/10 + 1 7/10 = 4 12/10 = 5 2/10 = 5 1/5

P = 5 1/5

L = P

c)

c - 2 2/3 = 1 1/2

c = 1 1/2 + 2 2/3 = 1 3/6 + 2 4/6 = 3 7/6 = 4 1/6

spr.

L = 4 1/6 - 2 2/3 = 3 7/6 - 2 4/6 = 1 3/6 = 1 1/2

P = 1 1/2

L = P

d)

4 1/8 - d = 2 5/6

-d = 2 5/6 - 4 1/8

d = 4 1/8 - 2 5/6 = 4 3/24 - 2 20/24 = 3 27/24 - 2 20/24 = 1 7/24

spr.

L = 4 1/8 - 1 7/24 = 4 3/24 - 1 7/24 = 3 27/24 - 1 7/24 = 2 20/24 = 2 5/6

P = 2 5/6

L = P
