tolong di jawab !!! beserta caranya!!!

Ubah menjadi desimal terlebih dahulu
6. 30 3/5 = 3.60
340% = 3.40

12.6 × 5.18= 65.268 - 26 = 39.268 + 3.60 = 42.868 ÷ 3.40= 12.608

7. 3 1/2 = 3.50
75% = 0.75
17.15 ÷ 3.50 = 4.90 + 14.86 = 15.76 - 0.75 = 15.01

8. 9 4/5 = 9.8
120% = 1.20
6.28 + 9.80 = 16.08 × 7.24 = 116.41 - 1.20 = 115.21
