a. 1 6/7+2 3/7=3 9/7= 4 2/7
b. 8 5/6+ 2 4/6= 10 9/6= 11 3/6 (skracanie) 11 1/2
c. 6 7/9 + 8 8/9=14 15/9= 15 6/9= (skracanie) 15 2/3
d. 1 3/4+ 2 3/4 + 3 3/4=6 9/4=8 1/4
e. 2 3/8+ 9 5/8 + 7/8=11 15/8= 12 7/8
f. 8 7/10+ 7 5/10+ 9/10= 15 21/10= 17 1/10
g. 5/12+ 3 8/12 + 5 7/12= 8 20/12= 9 8/12 =(skracanie) 9 2/3
LICZĘ NA NAJ :D
