1.a) 11i2/3-8i8/9=11i6/9-8i8/9=2i7/9
b) 4i2/3:6= 14/3*1/6=7/9
c) -3+(-2)*(-4)=-3+8=5
2.3,0(3)+1,(7)=3i3/99+1i7/9=3i3/99+1i77/99=4i80/99
Reszty nie umiem
zd1
11 2/3 - 8 8/9 = 35/3 - 80/9= 105/9-80/9 = 25/9 = 2 7/9
4 2/3 :6 = 14/3 ;6=14/3 * 6/1 = 84/3 =28
-3 +(-2)*(-4)= -3 + 8=5
zd 2
3,0(3) = 3 +0,0(3)
0,0(3)=x | *10
0,33... = 10x
0,3+ 0,0(3)=10x
0,3+ x=10x |-x
0,3=9x |:9
3/10:9 = x
3/10*1/9 = x
3/90 =x
1/30=x
x+3= 1/30 +3 = 3 1/30
1,(7) = 1 + 0,(7)
0,(7) =x | *10
7,(7) = 10x
7+ 0,(7) = 10x
7+x = 10x | -x
7= 9x |:9
7/9 = x
1+ 7/9 = 1 7/9
3,0(3) + 1,(7)= 3 1/30 + 1 7/9 =91/30 + 16/9 =819/270+ 480/270= 1299/270
