tolong jawab semua pertanyaan ini

1. 14/15 - 4/9 - 1/3 = 126/135 - 60/135 - 45/135
= 21/135
2. 2,8 - 135% + 9/25 = 28% - 135% + 36%
= -71%
3. 2.15 + 0,9 + 1,238 = 4,288
4. 8/15 × 0,24 = 8/15 × 24/100
= 192/1500
5. 35% : 1 3/4 × 5 2/3= 35/100 : 7/4 × 17/3
= 245/700 × 1225/700
= 1470/700
= 2 70/700
= 2 1/10
