Answer 1

1.) 11/15+2/15=13/15(karena penyebutnya udah sama, tinggal ditambah)
2.)8 9/6+1/9=8+(9/6+1/9)
=8+(27/18+2/18)
=8 29/18=9 11/18
3.)8 6/9+3 2/5
=11+(6/9+2/5)
=11+(30/45+18/45)
=11 48/45=12 3/45=12 1/15

Semoga membantu :')

Answer 2

1). 11/15 + 2/15 = 13/14

2). 8 9/6 + 1/9= 57/6 + 1/9 = 171/18 + 2/18 = 173/18 = 9 11/18

3). 8 6/9 + 3 2/5 = 78/9 + 17/5 =390/45 + 153/45= 543/45 = 12 3/45
