1. 2/3 + 7/12 = 2. 6/10 + 7/15 = 3. 5/8 + 5/12 = 4. 5/12 + 3/15 =

1. = 8/12+7/12=15/12
2. =18/30+14/30=34/30
3. =20/24+10/24=30/24=15/12
maaf no 4 cari sendiri

1. 2/3+7/12= 8/12+7/12
= 15/12
= 5/4
2. 6/10 + 7/15
= 18/30 + 14/30
= 32/30
=16/15
3. 5/8 + 5/12
= 15/24+10/24
= 25/24
4. 5/12 + 3/15
= 25/60+12/60
= 37/60
