Jawaban:

8. 3 + 1/23 - 2,25

= 3 + 1/23 - 225/100

= 69/23 + 1/23 - 9/4

= 70/23 - 9/4

= 280/92 - 207/92

= 73/92

9. 9 - 7,5 + 6/23

= 9 - 75/10 + 6/23

= 9 - 15/10 + 6/23

= 9 - 345/230 + 60/230

= 9 - 405/230

= 9 - 81/46

= 414/46 - 81/46

= 333/46

10. 9,25 - 3/110 + 7

= 925/100 - 3/110 + 7

= 37/4 - 3/110 + 770/110

= 37/4 - 773/110

= 2.035/220 - 1.547/220

= 488/220

= 122/55

Semoga membantu^^
