-6 -(-4 5/9)=
Proszę o zapisanie wszystkich obliczeń :) Dziękuję :3

Answer 1

7 1/3 +(-4 5/6)= 22/3- 29/6= 44/6-29/6=15/6=2 1/2
-5 4/7 +7= 39/7+7/1=39/7+49/7=88/7= 12 4/7
1,23-9= 1 23/100 -9/1= 123/100-900/100= 777/100= 7 77/100= 7,77
-6 -(4 5/9 )= - 6 + 41/9 = - 6/1 + 41/9= 54/9 + 41/9 = 95/9 = 10 5/9

Answer 2

7 1/3 + (-4 5/6) = 7 2/6 + (-4 5/6) = 2 3/6 = 2 1/3

-5 4/7 + 7 = 1 3/7

1,23 - 9 =  -7,77

-6 -(-4 5/9) = -1 3/9 = -1 1/3
Myśle że pomogłem :)
