Answer 1

1.   3i5/6+ 2i1/4=3i10/12+2i3/12= 5i13/12= 6i1/12

2.   6i2/3-4i2/4=6i8/12-4i6/12=2i2/12=2i1/6

3.   4i2/5-1i1/3=4i6/15-1i5/15=3i1/15

4.   2i3/4+7i7/8=2i6/8+7i7/8=9i13/8=19i5/8

5.   5i1/2+3i1/5=5i3/6+3i2/6=8i5/6

6.   2i1/6-1i2/3=2i1/6-1i4/6=1i7/6-1i4/6=3/6=1/2

7.   8i2/3-4i7/9=8i6/9-4i7/9=7i15/9-4i7/9=3i8/9

8.   5i3/5+3i7/10=5i6/10+3i7/10=8i13/10=9i3/10

mam nadzieję że nic nie pomyliłam

 

Answer 2

1. 23/6 + 9/4 = 46/12 + 27/12 = 73/12=6 i 1/12

2. 20/3 - 18/4= 80/12 - 54/12= 26/12=2 i 2/12= 2 i 1/6

3. 22/5 -4/3= 66/15-20/15= 46/12= 3 i 10/12= 3 i 5/6

4.11/4 + 63/8 = 22/8 + 63/8= 85/8=10 i 5/8

5. 11/2 +10/3= 33/6 + 20/6= 53/6=8 i 5/6

6. 13/6 - 5/3= 13/6-10/6= 3/6=1/2

7.26/3-43/9=78/9-43/9=35/9=3 i 8/9

8. 28/5+37/10= 56/10+37/10= 93/10=9 i 3/10

 

Na pewno dobrze, bo z tego dostałam 5 w klasie :d
