8.
3 i 7
9.
2(5/8)+1(7/8)=3(12/8)=4(4/8) =4(1/2) lub 4,5
10.
b) 3(6/7)+1(3/7)=4(9/7)=5(2/7)
c) 5(5/8)+2(3/8)=7(8/8)=8
d) 5(4/9)+7(7/9)=12(11/9)=13(2/9)
e) 1(3/4)+2(1/4)+3(3/4)=6(7/4)=7(3/4)
f) 2(5/8)+7(3/8)+2(3/8)=11(11/8)=12(3/8)
g) 8(7/10)+4(3/10)+(5/10)=12(15/10)=13(5/10)=13(1/2)
h) (5/11)+3(8/11)+4(10/11)=7(23/11)=9(1/11)
Z.8 1/9 + 8/9 = 9/9 = 1 11/7 + 3/7 = 14/7 = 2 2 + 1 = 3
2 3/4 + 2 1/4 = 4 4/4 = 5 1 3/8 + 5/8 = 1 8/8 = 2 5 + 2 = 7
Z.9 nie wiem
Z.10 b) 3 6/7 + 1 3/7 = 4 9/7 = 5 2/7
c) 5 5/8 + 2 3/8 = 7 8/8 = 8
d) 5 4/9 + 7 7/9 = 12 11/9 = 13 2/9
e) 1 3/4 + 2 1/4 + 3 3/4 = 6 7/4 = 7 3/4
f) 2 5/8 + 7 3/8 + 2 3/8 = 11 11/8 = 12 3/8
g) 8 7/10 + 4 3/10 + 5/10 = 12 15/10 = 13 5/10
h) 5/11 + 3 8/11 + 4 10/11 = 7 23/11 = 9 1/11
Mam nadzieje że pomogłam
