jawablah dengan caranya???? jadikan pecahan desimal

gambar nya jelas gak ?

13. 28/10 : 84/10 × 48/10 - 13/10 + 31/6
= 16/10 - 13/10 + 31/6
= 48/30 - 39/30 + 155/ 30
= 164/30
= 5,466
14. 22/5 + 375/100 : (35/10 - 11/6)
= 22/5 + 375/100 : (105/30 - 55/30)
= 22/5 + 375/100 : 30/50
= 22/5 + 225/100
= 440/100 + 225/100
= 665/100
= 6,65
