Odpowiedź:
a) 2:4 b) 2:9 c) 2 5:5 d) 1 e) 5:11 f) 0
Szczegółowe wyjaśnienie:
Zadanie nr 5
Uzupełnij :
a) x - 1/4 = 1/4
x = 1/4 + 1/4
x = 2/4
----------------------------------------------------
b) 7/9 - x = 5/9
x = 7/9 - 5/9
x = 2/9
c) x - 2/5 = 2 3/5
x = 2 3/5 + 2/5
x = 2 5/5
x = 3
---------------------------------------------------
d) 2 2/7 - x = 1 2/7
x = 2 2/7 - 1 2/7
x = 1
e) x - 5/11 = 0
x = 5/11
-----------------------------------------------------
f) 11/32 - x = 11/32
x = 11/32 - 11/32
x = 0

Verified answer
Zadanie nr 5
Uzupełnij :
a) x - 1/4 = 1/4
x = 1/4 + 1/4
x = 2/4
2/4 - 1/4 = 1/4
----------------------------------------------------
b) 7/9 - x = 5/9
x = 7/9 - 5/9
x = 2/9
7/9 - 2/9 = 5/9
----------------------------------------------------
c) x - 2/5 = 2 3/5
x = 2 3/5 + 2/5
x = 2 5/5
x = 3
3 - 2/5 = 2 3/5
---------------------------------------------------
d) 2 2/7 - x = 1 2/7
x = 2 2/7 - 1 2/7
x = 1
2 2/7 - 1 = 1 2/7
----------------------------------------------------
e) x - 5/11 = 0
x = 5/11
5/11 - 5/11 = 0
-----------------------------------------------------
f) 11/32 - x = 11/32
x = 11/32 - 11/32
x = 0
11/32 - 0 = 11/32
