b)2/7
-10
a)10
b) 1/10
3.2
a) -3,2
b) 10/32
-1.25
a) 1,25
b) 4/5
Zadanie 2. a) 3.1/3 + (-4,8) = 10/3-48/10 = 100/30-144/30 = -44/30 = -1 14/30 = -1 7/15
b) -2,8 + (-11.1/4) = -2,8-11,25 = 14,05
Zadanie 3. a= (3.2/5 - 5,4) * (3.1/4 + 2,75) = (3,4-5,4)*(3,25+2,75) = (-2)*(6) = -12
b=(2.2/9 - 4.1/3) : 3.1/6 = (20/9-13/3):19/6 = (20/9-39/9)*6/19 = -19/9 * 6/19 = -6/9 = -2/3
a < b
