Zadanie 9
a. z + 1/6 = 2 5/6
z = 2 5/6 - 1/6 = 2 4/6
b. 3/10 + x = 1
x = 1 - 3/10 = 7/10
c. 4 = y + 3 3/4
-y = 3 3/4 - 4
-y = -1/4
y = 1/4
d. 3 3/11 - z = 3
z = 3 3/11 - 3 = 3/11
e. 4 - x = 3 3/5
x = 4 - 3 3/5 = 2/5
f. y - 5 3/7 = 3 6/7
y = 3 6/7 + 5 3/7
y = 8 9/7 = 9 2/7
Zadanie 10
1/2 = 4/8
1/4 = 2/8
2/16 = 1/8
4/8 + 2/8 + 1/8 = 7/8
1 - 7/8 = 1/8
