tylko chciała bym rozpisane a nie same wyniki

Answer 1

a) -2 1/5+3,3= -2,2 + 3,3 = 1,1
b) 1 6/5-3 1/3=1 18/15 - 3 5/15 = 33/15 - 50/15 = - 17/15 = - 1 2/15
c)4,3-7,5 = - 3,2
d)-4,5-2 1/4= - 4,5 - 2,25 = - 6,75
e)-3 1/6 -(-5 5/6) = - 19/6 + 35/6 = 16/6 = 2 4/6 = 2 2/3
f)7 1/3 +(4 5/6) = 22/3 + 29/6 = 44/6 + 29/6 = 73/6 = 12 1/12
g)-5 4/7+7= 1 3/7
h)1,23 - 9 = - 7,77
i)-6-(4 5/9) = - 10 5/9
