1. 12 całych - 11 całych i 1/6 = ? 2.(7 całych + 2/9 ) - 1 cała i 3/9 = ? 3 całe - (5/8+1/8) = ? 3.(10 całych i 1/2 - 1/2) + ( 2 całe i 1/2 + 3 całe i 1/2 ) = ? Z góry dzięki ; dd

1. 12- 11 i 1/6= 5/6
2. (7+2/9)-1 i 3/9= 5 i 8/9
3-(5/8+1/8)= 3- 6/8= 2 i 2/8
3. (10 i 1/2 -1/2)+ (2 i 1/2 + 3 i 1/2)= 10+ 6= 16
1. 12-11i1/6=5/6
2. (7+2/9)-1i3/9= 7i2/9- 1i3/9= 5i8/9
3. 3- (5/8+1/8)=3- 6/8=2i2/8
4. (10i1/2-1/2)+(2i/1/2+3i1/2)= 10+6=16
